Cross Passage Construction: Eglinton Avenue East at Walder Avenue

 
juillet 11, 2016

What

A cross passage is a small passageway built to connect the eastbound and westbound tunnels for maintenance and emergency purposes. Dewatering equipment is used at street level on Eglinton Avenue above the cross passage location. Dewatering is the process of removing groundwater from around the tunnel level below. The dewatering equipment will be in place for the duration of the building of the cross passage.

Where

While the majority of work will occur underground within the tunnels, dewatering operations will be visible on the surface on Eglinton Avenue East near Walder Avenue.

Why

Dewatering wells are an important part of the cross passage construction process in order to make sure that the water table remains low enough to allow the hand mining required to construct the interconnecting passage outside the main tunnels.

When

Construction will take place in three stages, starting as early as the week of July 18, 2016 for approximately four (4) months.

3 stages of cross passage work

  • Westbound Eglinton traffic will be prohibited from turning southbound on Cleveland Street.
  • Eastbound Eglinton traffic will be prohibited from turning northbound on Walder Avenue.

In certain situations, some late night and/or early morning works may be required to complete the work and keep construction moving. The contractor will not always work during the extended hours, but may do so at its discretion.
