Dufferin Street Bridge Demolition and Installation of Temporary Crossing

DuffBridgeUpdate.JPG

Expected Project Start Date: November 1, 2013
Expected Completion Date: February, 2014

The City of Toronto will be carrying out bridge demolition and installation of a temporary crossing at Dufferin Street over the Metrolinx/GO Transit Rail Corridor, south of Springhurst Ave. The temporary crossing will provide access for pedestrians, cyclists and motorists. The construction of a new permanent bridge is currently planned for 2016.

The bridge is currently closed to vehicular traffic due to safety issues and will remain closed for the duration of the project. Pedestrians and cyclists will continue to have access to the bridge until further notice.

This work will take place near Dufferin Street, south of Springhurst Avenue.

Your co-operation and patience during the construction period is appreciated.

Construction Details

The project will involve the following:

• The demolition of the existing bridge superstructure;
• Reinforcement of the existing bridge abutments;
• Construction of new foundations for the modular bridges;
• The installation of three (3) temporary modular bridges – one (1) for northbound traffic, one (1) for southbound traffic, and one (1) for pedestrians;
• Modifications to the lighting on the bridges;
• The reconstruction of the bridge approaches;

City pavement tests have identified that asbestos is present in the asphalt on the Dufferin Street Bridge over the Metrolinx/GO Transit Rail Corridor.

Asbestos was used in asphalt mixes throughout the 1970s and early 1980s because it significantly improved the performance of the asphalt. Recent testing and air quality monitoring have confirmed that asbestos used in asphalt mix is bonded very tight, does not become separated during the asphalt removal operation, or become airborne to pose any harm to the health of those who are exposed. The City does require the contractor to follow the procedures established by the Ministry of Labour through the Occupational Health and Safety Act:


• Wetting down the pavement surface during asphalt cutting, grinding or removal and attaching dust collecting devices with HEPA filters to equipment , where possible, to minimize dust from becoming airborne;
• Workers are no longer required to use personal protective equipment such as disposable coveralls and respirators; however, the choice will be theirs as to whether they wear the equipment on site;
• Asbestos contained asphalt will be disposed at Ministry of the Environment approved disposal sites and transported accordingly.

All work will be completed within City property limits.

You will be notified if there are any significant changes to the construction schedule or work to be undertaken.

Work Hours
Work will typically take place from 7 a.m. to 7 p.m. from Monday to Friday, with work after hours and on weekends as required.

Disruptions
As with all construction projects, there will be noise and temporary inconveniences. In order to complete the work effectively and in a safe manner, some pedestrian and traffic restrictions will be necessary. These include continued closure of the bridge to vehicles for the duration of the project. Pedestrians will continue to have access to the bridge during the construction period. However, there may be certain operations that require the bridge to be closed to pedestrians. Advance notice of these closures will be provided.

Traffic Restrictions
Vehicular traffic will continue to be required to detour around the closure. Signage advising of the closure of the Dufferin Street Bridge has been placed on the street network to allow motorists to choose alternate routes. During periods where the bridge is closed to pedestrians and cyclists, signage advising of the pedestrian/cyclist detour will be placed on the street network.
