I-5 Construction Closes Main Street Carpool Ramp

Work has begun on the I-5 Central Project between SR-55 and SR-57.

The I-5/Main Street carpool on- and off-ramps have been permanently closed to allow crews to perform preliminary work leading up to the bridge demolition in early summer. Other activities include removing overhead signs, adjusting traffic signal adjustments, restriping lanes and installing concrete barriers on southbound Main Street, reducing it to two lanes near the Discovery Cube.

Motorists who normally use the Main Street carpool ramp can exit Broadway to get to Main Street. Refer to this map for other route options.

In addition, the existing auxiliary lane on northbound I-5 between Grand Avenue and 17th Street is closed to create room for a work area to construct new retaining walls and to install new concrete pavement. The Grand Avenue on-ramp and the 17th Street off-ramp remain open.

The work is part of a $41.6 million project to add a second carpool lane in each direction of I-5 between SR-55 to SR-57 to alleviate traffic congestion and bottlenecks.
