I-80 Getting New Bridge Over Susquehanna River

Major Interstate 80 bridge project under way in Columbia County

A five-year, $50 million bridge project on Interstate 80 in Columbia County is under construction this fall.

The contract includes a new westbound river bridge to be built between the
existing eastbound and westbound structures over the West Branch of the
Susquehanna River between Exits 241 (Lime Ridge/Berwick) and 242

The existing eastbound bridge there will get a new
superstructure (deck and beams).

In addition, rehabilitation work will take
place on the nearby bridges over the Canadian Pacific Railroad tracks and Route 339 to the east.

Prime contractor New Enterprise Stone & Lime Co., Inc. has begun building a
portion of the new river bridge on the east side of the river near Mifflinville
in the median area between the existing bridges.

The contractor has installed a rock causeway extending to approximately the
middle of the river, and is constructing six of 16 piers as well as the east-shore abutment. The contractor anticipates having those piers constructed and new bridge beams set by the beginning of April 2011. After the beams are set, the contractor will construct the bridge deck and parapets.

The rock causeway will then be moved to the west side of the river and the
remaining portion of the new bridge will be constructed.

Beginning next spring, new structures will be built in the median area on the
Mifflinville side of the river. One bridge spans the Canadian Pacific Railroad
tracks and one spans Route 339 at the Mifflinville Interchange (Exit 242).

After these bridges are built, along with the roadway between them, all traffic
– both eastbound and westbound - will be placed on the new structures in the
median (two lanes each direction). At that time the existing eastbound river
bridge as well as the existing eastbound structures over the railroad and Route
339 will be rehabilitated. The existing westbound structures will be demolished.

The contractor will maintain two lanes of traffic in each direction during most
of the construction.

All of this work is expected to be completed by the end of the 2014 construction season with final paving being done in the spring of 2015.
