Upcoming Construction Activities
Remaining major structural work includes construction of concrete median barriers and a retaining wall, as well as installation of new overhead signs. In addition, crews will construct a new barrier on the southbound side of the Main Street bridge over the freeway, where it was once connected to carpool ramps. The ramps were demolished in summer 2019. Construction is expected to be completed in early 2021.

LONG-TERM CLOSURE OF NORTHBOUND AND SOUTHBOUND I-5 CARPOOL LANES
The northbound I-5 carpool lane was closed between Grand Avenue and SR-57 on Friday, April 10 and the southbound I-5 carpool lane between Bristol Street/La Veta Avenue and First Street was closed on Wednesday, April 22. Caltrans has opened one carpool lane in each direction before they widen into two lanes as motorists approach the connectors. Specifically:
- From northbound I-5: One carpool lane is open from SR-55 to Main Street and two carpool lanes are open from Main Street to the SR-57 connector
- From southbound I-5: One carpool lane is open from SR-57 to Broadway and two carpool lanes are open from Broadway to the SR-55 connector
This interim configuration is expected to remain in place through the end of July.

Getting to Main Street
The I-5/Main Street carpool bridge was demolished in early August 2019 to make room for a second carpool lane on I-5 between SR-55 and SR-57. Motorists who normally use the Main Street carpool bridge can check out our Getting to Main Street map.
