Adelaide Street Underpass

The City is planning to reconstruct Adelaide Street from Central Avenue to McMahen Street. This will include an underpass beneath the CP Rail tracks, nearby intersection improvements and active transportation connections with wide multi-use paths added on both sides of the roadway.

The new street design will enhance the pedestrian and biking environment, improve safety, reduce traffic back-ups due to trains and improve access to transit. It is being designed to improve route reliability, efficiency and safety for everyone crossing the railway.

The City is planning to maintain two lanes of traffic during most of the construction period through a road detour to the east of Adelaide Street.

This project has received funding commitments from the Government of Canada and the Province of Ontario to support 10 transit and transit-supportive projects.

Project update

Advanced storm sewer relocation: The City is installing a new storm sewer in advance of 2021 construction, along the McMahen Park and CP Rail fence line. The work began on December 15, 2020 and is anticipated to take approximately one month, weather permitting. As part of this work, the horseshoe pits have been removed and will be relocated to a new location in spring 2021.

The location

Construction will take place along Adelaide Street from Central Avenue to McMahen Street.

The work

This project will:

  • demolish the gas station at 595 Adelaide Street
  • relocate utilities
  • replace existing underground infrastructure
  • install a new pump station for storm water runoff
  • realigning CP Rail tracks

The benefits

Construction will result in:

  • increased safety and efficiency of the Adelaide Street and Central Avenue intersection
  • new sewer infrastructure and a new utility corridor which will eliminate disruptive maintenance repairs
  • enhanced street lighting that will improve accessibility and overall street safety
  • the new McMahen Park entrance being elevated above Adelaide Street and separated from traffic
  • the addition of more trees that will create a more intimate park setting
  • the underpass easing traffic congestion and eliminating vehicle idling during train crossings
  • a decrease in cut-through traffic on adjacent neighbourhood streets.
  • the underpass, the cycling lane connection on Central Avenue and the proposed East London Link rapid transit route working together to improve the reliability of transit
  • a separated multi-use path along Adelaide Street which will include a cycling lane connection to the existing bike route on Central Avenue
  • a new multi-use path that will increase pedestrian safety by eliminating the need to cross the rail tracks
