The Olgiati Bridge on U.S. 27 will undergo routine maintenance this weekend.

TDOT survey crews will conduct an in-depth survey of the bridge this Sunday, January 11th, beginning at 6:00 a.m. and ending by 6:00 p.m. During the survey, the bridge will be reduced to one lane in each direction.

The 4th Street entrance ramp to U.S. 27 North will also be closed to traffic as the survey is performed. Detours will be posted.

The crews will be gathering detailed information about the bridge in anticipation of a future widening project.

Drivers wishing to avoid the area during the work are encouraged to use the Market Street Bridge or the Veterans Bridge as alternate routes.
