To ensure the safety of motorists and our maintenance and contractor construction crews, Caltrans schedules maintenance and construction work on highways and freeways throughout the district when traffic volumes are lower (yes, there is actually a part of the day when traffic volumes are lower in Los Angeles County).
Pacific Coast Highway (SR-1) at the junction with I-10 has an annual average daily traffic count (AADT) of 63,000 vehicles. I-10 has an AADT of 148,000 vehicles. That’s average of 105,500 vehicles a day!
Check our traffic census page for the AADT’s for routes statewide: http://www.dot.ca.gov/trafficops/census/
Last night (Sunday, July 31 into August 1), the tunnel washing crew removed soot from the walls and ceiling of the McClure tunnel. Crews removed graffiti from the walls, repaired the delineators on the center median, sealed cracks in the pavement, and removed vegetation along the landscape near the tunnel entrance and exit.
Within the next week, a paving project is expected to occur (we’ll provide more details once the schedule is approved by the district traffic management office engineers).
Caltrans will close all lanes of the SR-1/I-10 Interchange at the McClure Tunnel for tunnel washing, crack sealing, brush removal, tree trimming, sweeping, and graffiti remove on the following days and nights:
Sunday, July 31, 10 p.m. to 6 a.m.
Monday, August 1, 10 p.m. to 6 a.m.
Signed detours will be posted. Motorists should consider alternate routes and expect delays.
Example of the work (Twitter video from northbound I-405 to northbound I-5 connector):
