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.
