OCTA 405 Construction Update
The Orange County Transportation Authority, in cooperation with Caltrans, is widening the San Diego Freeway (I-405) between SR-73 and I-605.The project is improving 16 miles of I-405 between the SR-73 freeway in Costa Mesa and I-605 near the Los Angeles County line. Construction updates are as follows: Westminster Boulevard Traffic Shift
Crews will shift traffic to one side of the Westminster bridge over I-405 to begin the second phase of demolition and reconstruction. Crews will open some lanes on the new bridge, construct the center median, and then fully shift traffic to the new portion of the bridge. This work is anticipated for early-to-mid-January and will require bridge and ramp closures.
Partial demolition of the old portion of the bridge will occur over two weekends under full freeway closures and is anticipated for late January and early February.
The 405 Community Outreach Team will provide detailed closure, detour and schedule information in future alerts. Sign up for projectwide and bridge-specific construction alerts at bit.ly/405-signup.
Westminster On-ramp to Close for One Month
Crews will close the southbound I-405 on-ramp from Westminster Boulevard for about a month starting Jan. 4 at 10 p.m. to accommodate the freeway widening. Activities include demolition, excavation, 405
grading, drainage and electrical system installation, concrete pours and asphalt paving. For more information, email 405project@octa. net or call (888) 400-8994. Construction is occurring along the entire stretch of the I-405, so drivers should watch for detour signs.
