This project will provide a new driving surface on the bridge.  The work entails grinding off the top half inch of the bridge deck and providing one-and-a-half inches of new cement concrete overlay and installing new expansion joints.


The bridge remains open during construction. The work will be accomplished using half the bridge at one time. The other half will remain open for one lane of traffic in each direction.
