The Ontario Ministry of Transportation says it will cost $554,000 to repair the damaged Indian Rd. Hwy. 402 overpass, after a transport truck's oversized load collided with it in late November.
In an email to BlackburnNews.com, Communications Services Coordinator Emmilia Kuisma confirmed preliminary work began on the overpass March 7.
Traffic control measures have recently been put in place on the highway so work can begin immediately, with an estimated completion date in May.
Traffic travelling on eastbound Hwy. 402 will be the most affected during construction, with a single lane restriction for the duration of the contract.
There will be a single night, eight hour, full eastbound closure on a weekend in either late March or early April to allow for construction crews to replace the girders. It's expected the westbound lanes will be restricted to a single lane periodically throughout the contract, awarded to McLean Taylor Construction Limited of St. Mary's.
The County of Lambton previously announced temporary repairs in early January cost almost $100,000 for temporary restoration of two-way traffic.
The county is currently exploring legal avenues to get that money back.
Scarborough company Automatic Coating Limited and the truck driver, 55-year-old Terrance Hamilton of Scarborough, face charges in the November collision.
Their second court appearance takes place on April 8.
