I-5 Southbound Lanes Shut for 56 Hours as GSA Replaces Speed Bumps

At a Glance

  • GSA will close six I-5 lanes and an on-ramp for 56 hours starting Jan 6.
  • Speed bumps will be replaced with permanent dividers near the San Ysidro Port of Entry.
  • Drivers are urged to use the Otay Mesa POE to avoid delays.
  • Why it matters: Travelers crossing the border will face significant lane closures and delays for almost a week.

Border commuters heading south on I-5 will encounter a nearly week-long lane and on-ramp closure as the U.S. General Services Administration (GSA) begins work near the San Ysidro Port of Entry. The project, slated to start at 9 p.m. on Jan 6, will replace speed bumps with poured-in-place dividers and cost $2.7 million.

Construction Timeline

The project unfolds in two phases, each affecting different parts of the southbound corridor:

Phase Dates Closure Scope
1 Jan 6 9 p.m. – Jan 9 5 a.m. Camino de la Plaza on-ramp + six lanes north of San Ysidro POE
2 Jan 9 5 a.m. – Jan 23 5 a.m. Easternmost I-5 southbound lane

Impact on Commuters

Commuters have warned of chaos, with Border commuter Jose Medina predicting “un desmadre,” Spanish slang for chaos, and Josefina Aguirre calling the crossing a nightmare.

Administrator Edward C. Forst announced:

> “As the federal government’s landlord, GSA continues to invest in our land ports of entry and work jointly with regional partners to ensure our nation’s ports promote safe and secure trade and travel,” said Administrator Edward C. Forst. “We understand that construction can be disruptive, and we are working closely with Caltrans to minimize the impact on the traveling public and deliver these important improvements.”
