Kiernan bridge over Highway 99 to be closed at night

Starting Monday and continuing through Sept. 30, the Kiernan Avenue bridge over Highway 99 will be closed most nights for seven hours.

The full closure in both directions will let construction crews work from the bridge deck on the center column foundation, located in the highway median below. This work is a key piece of the third of four stages of the Kiernan Avenue interchange reconstruction project.

Electronic and print signs will guide motorists, bicyclists and pedestrians to detours at the Hammett Road bridge to the north and the Pelandale Avenue bridge to the south.

Each night when work is being done, the bridge will be closed from 10 p.m. to 5 a.m. the following morning. The closures will not occur on Friday or Saturday nights or holidays.

The interchange is getting a $44 million upgrade that will make the bridge 50 feet wider, adding a lane in each direction on Kiernan and another lane in each direction of Highway 99 between Kiernan and the Pelandale interchange to the south. The work includes local road improvements at Sisk Road and Salida Boulevard and construction of a storm drain pump station. The upgrade should be done in fall of 2016.
