Arterial Roads

T​oronto has not built any major roads since 1971 when construction of the rest of the Allen Expressway was cancelled. The only new road to be built since then was Black Creek Drive and that was constructed by the Provincial Government in 1982. The lack of road construction has been due to political reasons. Toronto's traffic has grown three times since the 1970's and congestion levels are reaching gridlocked proportions. It is time for Toronto to start building roads again in addition to subway construction, but on a moderate scale and only using existing available corridors such as under existing arterial roads, along existing rail and hydro corridors in order to preserve neighbourhoods and not demolish homes or businesses. Electric self-driving cars are the way of the future and new roads will be needed to accommodate them.

The Province of Ontario built and maintains a system of Provincial Freeways including the QEW and the 400-series Highways. Highways 400, 401, 404, 409 and 427 are the Provincial Freeways within the City of Toronto’s boundaries. The Province transferred the Toronto section of the QEW (now part of the Gardiner Expressway) and Highways 2A and 27 (now an arterial road) to the City of Toronto in 1997.

Toronto built the Gardiner Expressway east to Leslie Street, the Don Valley Parkway north to Highway 401 and the Allen Expressway (originally the Spadina Expressway) only as far south as Lawrence Avenue between 1954 and 1971. Plans were drawn up to extend the Allen Expressway to Bloor Street, extend the Gardiner Expressway east into Scarborough and extend Highway 400 south to the Gardiner.

These plans were abandoned as the City stopped building expressways in 1971 when further construction of the rest of the Allen Expressway was cancelled due to protests for neighbourhood preservation. The Allen was, however, later extended as an arterial road from Lawrence Avenue to Eglinton Avenue, as the right-of-way had already been prepared for it, hence the current name of Allen Road. Cancellation of the rest of the Allen also affected other planned GTA expressways at that time. However, without constructing less damaging alternate expressway routes, this decision has been considered the most devastating blow to growth and mobility in southern Ontario. Highway 400 was extended only to just south of Eglinton Avenue, but as an arterial road known as Black Creek Drive and the section of the eastern Gardiner Expressway between the Don River and Leslie Street was demolished in 2001 as it was under-utilized and would not be extended.

In 2000, the City of Toronto adopted the Road Classification Plan as part of the Official Plan. That report gave a specific classification for each road in Toronto as expressway, major arterial, minor arterial, collector and local road. The Gardiner Expressway, Don Valley Parkway, Allen Expressway from Eglinton Avenue to Transit Road, just north of Wilson Avenue, and Highway 2A are classified as ‘expressways’ due to their important function within the City’s overall transportation infrastructure inventory. This is enshrined in the City's Official Plan and the expressway status of these roads must be maintained.

Major missing links in the roads system exist in the northwest and in the east which can be served by minor new arterial road links, providing a continuous arterial roads system.

Proposed Arterial Road Links

Gaps in the arterial road grid also need to be filled in to maintain a continuous network of streets which carry buses, pedestrians and bicycles as well as cars. Breaks in Toronto’s arterial road system grid, especially in the Leaside, Beaches and Junction areas, must be linked to improve mobility and provide more direct bus services. No new roads should be built in the Rouge Valley Park which should be preserved in its natural state. There are several identifiable gaps in Toronto's arterial road grid which need to be addressed.

Building Underground Automated Highways

Will taking the highway one day involve closing your eyes and letting automated systems drive you through a system of subterranean tunnels?

There's a great deal of support for the underground automated highway system concept, and futurists and transportation experts alike have been forecasting aboveground automated highway systems (AHS) for decades. Most experts agree that when it comes to letting machines drive you through underground tunnels, it's probably more a question of when, rather than if.

Experts predict we're somewhere between 50 and 100 years away from the reality of taking the UAH to grandma's house. Creating such a transportation system, perhaps in the United States or Europe, would be a massive undertaking and to pull it off, we'd need to experience advancements in three major fields:

1.    A working automated highway system: As the saying goes, you have to learn to crawl before you can walk. For the majority of society to start using a UAH, they would first need to embrace the system and technology aboveground. And appropriate vehicles would be an essential part of any automated highway system. For instance, you couldn't launch a hovercraft-only lane on the interstate this year and expect everyone to drive in it. People would have to gradually become accustomed to the technology, purchase new hovercrafts and, if possible, update old vehicles to the new hovercraft standard. If AHSs were introduced slowly, the necessary vehicle guidance technology would have enough time to properly develop and catch on with mainstream consumers. This way, by the time the first UAH is introduced, enough drivers will be able to use them.

2.    Zero-emission vehicles: Automated or not, an underground highway would involve a great deal of traffic whizzing through subterranean passages. Such a system would be challenging to ventilate without having to pump out clouds of vehicle exhaust. You'd need vehicles that produce zero emissions through the use of fuel cells, batteries, solar power, hydrogen power or other energy-efficient methods.

3.    Improved tunnel-boring technology: Obviously, the creation of an underground highway is going to involve a great deal of digging. The Channel Tunnel, which runs 31 miles (50 kilometres) underneath the English Channel, took four years to complete [source: Encyclopaedia Britannica]. Imagine how much time it would take to complete a tunnel running the 2,776 miles (4,468 kilometres) between New York and Los Angeles? Some experts also contend that fully automated tunnel-boring technology would need to be perfected before UAHs could become a reality.

How does our current technology stack up against this list? 

According to the U.S. Department of Transportation Federal Highway Administration, the country's highways cover 160,000 miles (256,000 kilometres), carrying hundreds of millions of vehicles. Each year, more than 40,000 individuals die on these highways, costing the nation $137 billion. If you consider that human error is the leading cause in 90 percent of crashes, creating automated guidance systems makes more sense than ever [source: Turner-Fairbank Highway Research Center]Building Underground Automated Highways

Automated Traffic Underground

Each year, researchers make new strides in a number of technologies that would play a huge role in diverting automated traffic underground. Some of the existing technology is very promising, suggesting we might actually embark on our first subterranean road trip sometime in the next century.

When it comes to designing an aboveground automated highway system, much of the technology has been around for more than a decade. In the 1990s, the U.S. Department of Transportation sponsored the National Automated Highway System Consortium (NAHSC), which resulted in a very promising demonstration of current technology. The NAHSC equipped eight cars with several different automated driving systems. These included radar to detect other vehicles and magnetic and visual sensors to follow a length of highway marked with buried magnetic sensors and visual markers. Over the course of the demonstration, these vehicles traveled a combined 8,000 miles (­12,875 kilometres) and carried 4,000 passengers without incident [source: Smart].

Realizing the dream of self-driving cars will involve developing improved collision avoidance systems (versions of this are already on the market in some vehicles), artificial intelligence and automated, real-time routing systems. Experts predict that the first examples of automated highway systems will emerge in the form of special lanes, similar to high occupancy vehicle (HOV) lanes, designated for automated commercial trucking operations. From there, as the technology becomes more reliable and available, civilian use of AHS technology will steadily grow.

On the zero emissions front, a number of major automobile companies and private design groups are working diligently to create cleaner and more efficient fuel systems for vehicles. From General Motors' hydrogen-powered Hy-wire to the Reva G-Wiz Automatic Electric Vehicle currently available in India and the United Kingdom, the technology is steadily becoming more practical and efficient.

But what about automated tunnel-drilling technology? While you might think the idea of massive, robot worms drilling their way through the earth sounds like something from the age of Morlocks, the technology is not that far off. Several countries have continued to pursue tunneling projects and associated technologies during the last decade, leading to a decrease in tunneling costs and an increase in efficiency. Recent tunneling costs have dipped as low as $1.50 per cubic foot, and the latest tunnel-boring machines can tunnel through various terrains at a rate of 20 feet (six metres) per hour [source: Smart].

­Most researchers agree that improved earthquake protection systems must be developed to ensure the safety of UAH travelers. However, designers are encouraged by past incidents where underground structures moved with the land during quakes, resulting in relatively little damage. In fact, after an earthquake struck Japan in 1995, underground projects were the least damaged structures in the city of Kobe. A massive tunneling project would also create a great deal of dirt and rock, which would need to be relocated elsewhere. Planning where to transport it would be a challenge, but using the theoretical AHS on the surface would expedite the process of moving this earth to its final drop point.

Cross-Toronto Tunnels

Six-lane tunnelled highways should be constructed as an extension of Highway 400 south to the Gardiner Expressway near the western end of Front Street; and an extension of the Gardiner Expressway east to Birchmount Road and Danforth Avenue in Scarborough. These routes would be entirely privately-financed, privately-constructed and tolled.

It would be built in stages over several years starting from the northwest. The provincial Government should lease the right-of-way under the Metrolinx GO Lakeshore East and Kitchener rail corridors to a private company which would assume construction and maintenance of the entire route. 

The 9-km Highway 400 tunnel would extend south under Black Creek Drive and the Kitchener GO rail line and Union-Pearson Express rail line to the Gardiner Expressway near the western end of Front Street at Bathurst Street, thus giving drivers from downtown a quick access to Toronto’s northwest.

Black Creek Drive is experiencing severe congestion because it is carrying highway traffic and the road is too small with signalized intersections. The tunnel would solve this problem by moving the traffic underground. Black Creek Drive, immediately above, could then be downgraded and become more of a local road serving the local community. It would be relieved of the heavy 400-bound traffic that it carries now. 

The tunnelled route in the east should extend from the end of the Gardiner Expressway at the Don River east to Birchmount Road and Danforth Avenue, entirely in a 10-km tunnel. The existing six-lane Kingston Road will serve to connect to Highway 401 in the east for now.

 Eventually, all of the sections of the tunnels could be linked up in the middle by moving the elevated Gardiner Expressway underground, either under the Metrolinx Lakeshore rail corridor or under the lake. This would make the routes into one continuous tunnel across the City and remove the elevated Gardiner Expressway. However, this is a more long-term consideration Toronto needs more expressways in two directions: in the northwest and in the east. Underground toll tunnels can be utilized to complete the unfinished expressways: Allen Expressway south to Exhibition Place and north to Highway 407; Highway 400 to the end of Front Street at Bathurst Street; and the Gardiner Expressway east to Highway 401 in Scarborough.

Streetcars in mixed traffic should be phased out as this causes congestion. Streetcars should be replaced with energy-saving trolleybuses which, unlike streetcars, can maneuver around street blockages.

The proliferation of bicycle lanes on major arterial roads by removing traffic lanes should cease. This is not safe and reduces needed road space. Bicycle lanes should be placed along minor and local roads. They can be placed along major roads if traffic lanes are maintained and not removed. College Street is an example where this works well. There are two through traffic lanes and bicycle lanes on either side. Everything runs smoothly. An extensive network of off-road cycle trails as proposed in this plan will reduce the need for bicycle lanes on streets and increase cyclist safety. 

Building roads actually does a good job of cutting traffic congestion, and not just building expensive public transit. See this article from Toronto's Globe and Mail newspaper from 2013: Sick of Congestion? Build roads not transit.

The following extensions to Toronto’s arterial roads system are recommended:

  • Rathburn Road bridge over Etobicoke Creek into Mississauga.
  • Meadowvale Road bridge over Highway 2A and north to Steeles Avenue.
  • Keele Street extension to Weston Road from Rogers Road.
  • A new bridge over CN/CP rail to connect Roncesvalles Avenue with Old Weston Road.
  • Direct Kingston Road to Lake Shore Boulevard connection west of Coxwell Avenue.
  • Lawrence Avenue East connection at Bayview Avenue.
  • Morningside Avenue northern extension to Steeles Avenue.
  • Danforth Road extension to Gerrard Street East.
  • Extension of Weston Road from Royal York Road to Islington Avenue.
  • Extension of Leslie Street southerly to Overlea Boulevard
  • Connection of Dufferin Street across the Downsivew Air Base between Wilson Avenue and Sheppard Avenue West
  • Extension of Lawrence Avenue East into Pickering to connect with Bayly Street

A new Scarborough Expressway

Lands acquired along the original Scarborough Expressway route beside the Lake Shore East GO rail line are now no longer available. They are also discontinuous and do not extend west of Victoria Park Avenue. Therefore, the original route can no longer be considered, even for an arterial road. The opportunity exists to construct a new expressway to the east between the east end of the Gardiner Expressway at the Don Valley Parkway and Highway 401 at Port Union Road utilizing other existing corridors and not requiring the demolition of any properties. The following three options are available:

A 23 km tunnel under Kingston Road.

This would run under the Lakeshore East GO rail corridor from the Don River to Warden Avenue and Danforth Avenue and then turning east under Danforth Avenue and then under Kingston Road to Highway 2A at Highland Creek, which connects into Highway 401. The Kingston Road corridor west of Warden Avenue is too narrow, so using the railway corridor west of this point is advisable. Access and egress can be provided by simple one-lane ramps up into and down from Kingston Road.

A 12 km roadway along the Gatineau Hydro Corridor.

The road can be a scenic tree-lined parkway like those existing in Ottawa. It can connect to Bayview Avenue at Pottery Road in the west, the Don Valley Parkway south of Eglinton Avenue and to the north end of Woodbine Avenue at O'Connor Drive, providing a separate connection to the Gardiner Expressway via Woodbine Avenue and Lake Shore Boulevard. At the east end, it would connect to Highway 401 at Morningside Avenue and to Morningside Avenue for going north into Markham. Access and egress can be by provided by traffic signals, roundabouts or ramps at any of the arterial roads which cross the hydro corridor.

A 15 km bridge in Lake Ontario 2 km out from the shoreline.

Another corridor option is the lake. A Florida Keys style of bridge can be constructed parallel to the shoreline, 2 km out from the shore, from Leslie Street at the north end of the Leslie Street spit continuing east to connect to the south end of Morningside Avenue and further east to the south end of Port Union Road. Access and Egress can be provided at these three points and also at access bridges extending out from Victoria Park Avenue and from Brimley Road at Bluffers Park. This route would have a spectacular view of the Scarborough Bluffs, opening it up to tourists, and raised high points in the bridge can be provided to allow sailboats to pass under. Man-made islands can be constructed at various points along the route for fishing and picnics. The bridge would be far enough out to not interfere with the beaches. A similar bridge can be provided in the west end across Humber Bay from the CNE grounds to the Humber River as a relocated Gardiner Expressway or Lake Shore Boulevard. This would also offer a spectacular view of the downtown Toronto skyline from the west.

A combination of any of these options can also be considered.
