Work to repair sections of the concrete deck of the West Dartmouth Avenue Bridge over the South Platte River will result in partial closure in the eastbound lanes but one westbound lane will remain open throughout the project.

The work on the bridge deck is scheduled to begin about noon May 16 and the project is expected to be completed on the morning of May 19 when one lane in each direction will be opened. Full traffic flow is scheduled to be restored by May 20.

Plans are to detour traffic to either Hampden or Evans during the lane closures.

The Dartmouth Bridge over the South Platte River was started in 1964 but the work was swept away by the 1965 flood. Work began again on the bridge and the span of one land in each direction was completed in late 1965.

The route is a major east-west thoroughfare and the bridge was widened to two lanes in each direction in the 1970s.

While the steel structure of the bridge is sound, the impact of the weather and the heavy traffic flow has taken a toll on the bridge and the concrete deck is deteriorating.

Rick Kahm, public works director, has sought funds to rebuild the bridge deck. The estimated cost of rebuilding the bridge deck is $1.2 million. Kahm, on behalf of the city, applied to Colorado Municipal League for funds.

At the same time, in case the city didn't get the grant, Englewood had a design engineer develop a pilot project to repair a section of the bridge deck.

The city didn't get the grant but Englewood did budget $100,000 for the pilot bridge section replacement project scheduled to get underway on May 16.

“The first step is for the contractor to strip away the asphalt in order to inspect the concrete bridge deck,” said Larry Nimmo, public works field operations administrator. “An engineer will inspect the concrete and determine the best way to rebuild the deck. When the deck is completed, we'll put down a new asphalt road surface.”
