A $4.3 million contract to replace the 78-year-old bridge that carried Niagara Falls Boulevard over Bergholtz Creek in the towns of Niagara and Wheatfield in Niagara County has been completed, the state Department of Transportation announced.

The new, wider bridge carries four 12-foot-wide travel lanes and a continuous two-way center turn lane, matching the rebuilt section of Niagara Falls Boulevard south of the bridge. The old bridge carried four 10-foot-wide travel lanes.

The bridge provides 5-foot-wide shoulders and a sidewalk on its south side for pedestrians and bicyclists. The project, which began in the spring of 2011, also included resurfacing of Niagara Falls Boulevard from Military Road to Cayuga Drive Extension.

The construction contractor was Concrete Applied Technology Corp. of Alden, Erie County.

Commissioner Joan McDonald of the DOT said the expanded configuration of the bridge “enhances safety for all users.”
