La Salle Street Bridge testing over the Chicago River will require intermittent street closures Tuesday morning throughout the early afternoon.
The closures, beginning at 9 a.m. until noon, will cause closures of the bridge to pedestrian and vehicle traffic, according to a statement from the Chicago Department of Transportation.
Drivers and pedestrians can use the Clark Street Bridge to travel south or the Dearborn Street Bridge to travel north, CDOT said.
