Travelers using the San Ysidro Port of Entry to head into Mexico should expect delays this week as part of an ongoing renovation project at the border crossing into Tijuana.
Beginning Sunday at 10 p.m., three lanes of southbound Interstate 5 just north of the border will be closed.
The closure of the easternmost lanes will be effective until Friday at 6 a.m. according to The California Department of Transportation.
The multi-year project expanding lanes and inspection booths is to prepare for what the San Diego Association of Governments (SANDAG) projects will be an 87% increase in traffic by 2030.
Mexico completed its side of the border project last year.
It's estimated at least $226 million will be needed to complete the improvements on the U.S. side.
