Metrolinx has completed construction of the new rail bridge at Milliken GO.
Since spring 2019, trains have been running on a temporary diversion track to allow for construction of the new rail bridge at Milliken GO. Crews used top-down style construction, which involved constructing the bridge structure prior to completing the majority of the excavation for the underpass of the bridge.
Construction for the new rail bridge included installing the bridge pier, completing the bridge abutments and constructing the bridge deck on ground level.
The EllisDon crew completed construction of the new railway bridge deck – a significant milestone on the project.
Over the Oct. 16th weekend, crews implemented a major track closure at Milliken GO which allowed for decommissioning the temporary diversion track and shifting trains to the new east track.
As of Oct. 19, customers passing through Milliken GO are traveling on the permanent new east track atop of the new rail bridge. Milliken GO customers will board their trains from a new temporary platform adjacent to the previous platform. The previous track platform will be closed so construction on the new west platform can continue.
With this accomplishment under their tool belts, construction crews can now move onto achieving the next set of milestones. Completing phase 1 of the roadway excavation is next, which includes the area underneath the bridge deck. Crews will also work on the remaining utilities which includes removing and decommissioning a large watermain on Steeles Avenue East.
Improvements at Milliken GO have been progressing well and the shift to the new east track alignment allows crews to advance work at the station.
With more room to work, crews are now moving forward with building the new track platforms. Other passenger upgrades at Milliken GO Station will include pedestrian tunnels, elevators, weather canopies and lighting.
Pedestrians on Steeles Avenue East will have safer access crossing the road and getting to Milliken GO via stairwells and elevators that connect to the pedestrian bridge.
With two tracks, Metrolinx is one step closer to providing more frequent all-day, two-way GO service on the Stouffville line.
