Repairs to the Route 140 bridge at the Baltimore and Carroll county line will begin this week, but drivers shouldn't expect to see traffic delays until the spring, according to a news release from the State Highway Administration.
The $7 million bridge rehabilitation project includes replacing the driving surface and supporting steel beams, while widening the shoulders of the bridge over the North Branch of the Patapsco River.
Project completion is anticipated spring 2015, weather permitting.
Beginning early spring and continuing through fall 2014, the bridge will be reduced from four to three lanes, one of which will be a reversible lane carrying traffic toward Baltimore during the morning rush hour and toward Westminster during the evening rush hour and weekends, according to SHA.
"SHA is using an innovative approach to maintain traffic during construction to minimize impacts to drivers," District Engineer Dave Coyne said. "Beginning spring 2014, crews will need to block one of the four lanes to safely work on the bridge during construction, so SHA will require the contractor to use a movable barrier wall. There will be two eastbound lanes and one westbound in the morning and it will be reversed for the evening commute."
All four lanes of traffic will be maintained this fall and winter while crews widen the bridge and its approaches on the westbound side. Motorists may encounter temporary single-lane closures on Route 140 during the overnight hours later this week or early next week to allow crews to set up barrier walls along the westbound should and shift traffic lanes about two feet toward the eastbound shoulder.
The project is part of SHA's ongoing statewide bridge system preservation program. The bridge was constructed in 1946 and while structurally safe, it is showing signs of deterioration and needs rehabilitation.
