Project Description

The Liberty Bridge rehabilitation project began in 2015 with survey work and platform installation.  Deck replacement work and ramp reconstruction will begin in late April 2016.  Two lanes of traffic will be maintained in the direction of peak travel and a single lane of traffic will occur in the opposite direction.  Overnight single-lane restrictions in each direction will occur.  Long-term closure of the ramps to and from the Boulevard of the Allies will occur and detours will be posted.  Phased work will begin on the far right northbound (inbound) lane and progress across the bridge through 2016.  Other improvements include structural steel repairs and painting, concrete repairs, signage improvements and the installation of a new alternating overhead lane control system.  The project will continue through 2017 and include five (5) weekend and 26 overnight closures of the bridge, and 80 day closure of the Boulevard of the Allies in the bridge area, additional ramp closures and single-lane restrictions on the bridge and on Second Avenue next year.

2018 Update

Painting operations will continue in 2018 on the Liberty Bridge rehabilitation project.  Single-lane restrictions will occur as needed during off-peak hours and at least two weekend closures will occur to install the overhead lane control system and message boards.  Completed work includes expansion dam replacement, a latex overlay and deck replacement, structural steel and concrete repairs, and signage improvements.  Overall work will conclude in August 2018.
