SANDAG and Caltrans began five nights of overnight closures of northbound Interstate 5 in University City on Sunday evening, the second such closure in the past week.

Work crews will close northbound I-5 from state Route 52 to Genesee Avenue from 9:30 p.m. to 5 a.m. each night though Thursday, according to SANDAG.  Drivers will be detoured onto eastbound Route 52 and then northbound Interstate 805.

The agencies completed similar closures June 18-20. The closures are necessary to continue removing wooden structures that supported the recently completed construction of a trolley overpass at Voigt Drive.

The closures are part of the $2.17 billion Mid-Coast Trolley Blue Line Extension, which includes an 11-mile extension of trolley service by San Diego’s Metropolitan Transit System from Linda Vista to University City. The extension will add nine new stations from Mission Bay Park to Westfield UTC.

SANDAG is receiving $1.04 billion in funding from the Federal Transit Administration to complete the project.

The extension and related projects are intended to reduce traffic congestion as the county’s population increases. Construction on the extension began in 2016 and is scheduled to be completed in 2021.
