Caltrans is warning drivers that a portion of the Interstate 805 in the Sorrento Valley area will be closed again this weekend, this time in the opposite direction.

The closure follows last weekend’s detour of southbound lanes in the same area. Caltrans says the construction is due to culvert replacement underneath the freeway, pavement upgrades and roadside safety enhancements.

The upgrades are part of a $53.7 million State Highway Operation Protection Program project, with $47.6 million from Federal funds and the remaining $6.1 million from State funds.

The closure will not affect bus service nor trolley service in the area.
