The Harrison Street Bridge over the Chadakoin River in the city of Jamestown will be closed to traffic starting July 1 for a replacement project. The bridge replacement is scheduled to last about five months with a plan to re-open in November.

Harrison Street, between Foote Avenue and Main Street, will be closed to traffic during construction and a detour will be posted utilizing Foote, Main, Second and Fourth streets. A separate truck detour will be posted as well due to the low clearances on the Railroad viaduct on Foote and Main streets.

“The existing bridge has severely deteriorated as the original stone bridge foundations have reached the end of their useful life,” said Brad Bentley, Chautauqua County director of Public Facilities. “When the replacement bridge is in place, the Harrison Street Bridge will have a safe crossing with no structural deficiencies and an expected service life of 50 to 75 years.”

The Harrison Street Bridge replacement project was submitted by Chautauqua County Department of Public Facilities to New York State Department of Transportation and was selected by the NYSDOT as a Locally Administered Federally Aided project.

The project is estimated to cost $3 million.

“The Chautauqua County Department of Public Facilities understands that this bridge replacement project will be an inconvenience to the traveling public and has made efforts to minimize the length of the time to complete this important infrastructure project,” Bentley said.
