Summary of work

Construction will start in the spring of 2022. This project will completely reconstruct Hwy 43/Mankato Ave. from Sugar Loaf View to Belleview St. including portions of Sarnia St. Roundabouts will be constructed at the Hwy 61/Hwy 43 intersection as well as three additional intersections along Mankato Ave. including Riverbend Rd., Frontenac Dr. and Sarnia St.

Stages of construction

  • Stage 1: Work adjacent to the main roadways and a portion of the box culvert replacement located just south of Sarnia St. at Gilmore Creek.
  • Stage 2: Creates one lane of traffic in each direction on Hwy 61. There will also be some work on the north side of Sarnia St.
  • Stage 3: Reconstructs a significant portion of the Hwy 61/Hwy 43 intersection as well as the eastbound lanes on Hwy 61, East Lake Blvd., the west side of Mankato Ave. from Sugar Loaf View to Frontenac Dr. and the east side of Mankato Ave. from Frontenac Dr. to Belleview St.
  • Stage 4: Reconstructs the east side of Mankato Ave. from Sugar Loaf View to Frontenac Dr., the west side of Mankato Ave. from Frontenac Dr. to Belleview St. and the south side of Sarnia St.
