Construction milestone in south Barrie-Highway 400 overpass project

The overpass is being built to ease traffic congestion and promote growth in Barrie's south end

Bridge girders are being installed this week to add to the Harvie Road/Big Bay Point Road/Highway 400 crossing currently under construction.

A total of 26 girders will be installed overnight May 12, 13 and 14, weather permitting. As a result, Highway 400 will be closed in both directions between Mapleview Drive and Essa Road for intervals of 15 minutes between 10 p.m. and 6 a.m. The girders are each 2 metres high and about 45 metres long, 13 of them spanning the northbound lanes and 13 across the southbound lanes.

Over the last five months, the following work has taken place on this project:

  • ​​preparation of concrete forms and placement of structural steel for the bridge abutments​
  • delivery of fill material for the Harvie Rd. and Big Bay Point Rd. embankments
  • installation of storm sewers and watermains on Harvie Rd. west of Highway 400​

The goal of the project is to help ease traffic congestion and support growth in Barrie’s south end by connecting Harvie Road to Big Bay Point Road across the 400. The crossing is expected to open this fall.
