CONCORD — Freeway repair work by Caltrans will cause the partial closure of a major East Bay freeway interchange this weekend.
Two lanes connecting southbound Interstate 680 to the eastbound Interstate 580 connector ramp will not be open beginning at 9 p.m. Sunday. The shutdown will last until 5 a.m. Monday, with the lanes open in time for the morning commute.
Caltrans will detour drivers on southbound I-680 at the Stoneridge Drive exit, south of the connector ramp. Those drivers than can go left on Stoneridge Drive and use a right-lane entrance to get back onto northbound I-680. From there, drivers can catch the eastbound I-580 connector ramp.
Detour signs will be posted, and message boards will be lit to notify drivers ahead of the shutdown.
