In Fall 2016, crews started support of excavation (shoring) works at both the Main and Secondary Entrance sites of the future Mount Pleasant Station. The next step is to begin utility relocations and shoring of the station box in the roadway. Crews will complete work on the north side of Eglinton Avenue East first, then flip to the south side.
Shoring is a common step in the process of constructing the foundation of a building. Shoring involves installing steel piles, as well as braces and tie-backs, around the perimeter of the area being excavated to support the ground while crews dig. The station box is the area underground where future passengers will wait on the platform to board the Eglinton Crosstown LRT trains.
Utility relocation is also a common stop in the process of building new infrastructure. There is often a variety of critical utility infrastructure – both underground and overhead – within or near construction sites. Utility infrastructure could include hydro lines for electrical power, telecommunications cables for telephone and internet, water lines, and storm and sanitary sewers. Often times these utilities need to be relocated to ensure service continues while construction activities occur.
Setting up the work zone in the roadway will require some changes to the Mount Pleasant Road and Eglinton Avenue East intersection. Lane reductions will be required, and a minimum of one lane in each direction will be maintained for traffic. The closure of at least one crosswalk at the intersection will be required during construction. New turn restrictions may be implemented at this intersection and surrounding intersections to ensure safe traffic movements while there are reduced sight lines.
Later this Spring 2017, Metrolinx and our constructor, Crosslinx Transit Solutions, will issue more specific details on this work.
