The Maryland State Highway Administration (SHA) will soon begin a two-year bridge rehabilitation project on the I-495 Northwest Branch Bridge between MD 650 (New Hampshire Avenue) and MD 193 (University Boulevard) in Silver Spring. The existing structure was built in 1967 and its deck is showing signs of deterioration. Construction will begin this spring and should be completed in the fall of 2012, weather permitting.
Repairs include replacing portions of the existing concrete bridge deck. SHA will also replace the traffic barriers, install new concrete to resurface portions of the bridge deck not being replaced, and resurface the approach roadway once bridge work is complete.
Crews will manage construction in eight phases, incorporating multiple lane shifts for the duration of the project. Pattern changes include a temporary traffic split around the work zone and temporary lane shifts on both sides of I-495.
