MASON CITY, Iowa – Feb. 13, 2018 – A project to replace the bridge over the East Branch of the Iowa River on U.S. 69 approximately 4 miles north of U.S. 18 in Hancock County will require closing the roadway to traffic from 8 a.m. Tuesday, Feb. 20, until Sept. 3, weather permitting, according to the Iowa Department of Transportation’s Mason City construction office.

The contractor is starting early so they do not disturb the river under the bridge during the Topeka shiner spawning season, which is between May 15 and July 31. Starting the bridge replacement work early will allow the contractor to complete the substructure prior to May 15.

Graves Construction of Spencer is the contractor for the $982,121 project.

During this closure, motorists will be detoured around the construction zone using Hancock County roads B-30, R-44, and B-16.

The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
