|Tunnel washing truck in action on NB I-405 transition to NB I-5 in San Fernando 7/19/2016|
Well, it is a tunnel washing project and there's more to come on other routes in Los Angeles County.
Caltrans will close up to two lanes of northbound Arroyo Seco Parkway (SR-110) to wash the walls and ceilings of the four tunnels near Dodger Stadium from 10 p.m. to 5 a.m., Wednesday, July 20 to Friday, July 22.
A signed detour will be in place. Delays are expected. Closures are subject to change.
A Caltrans tunnel washing crew using a specially outfitted truck with water jets and carwash-like brushes will scrape away dirt, soot, and grim from the concrete walls of the interchanges and tunnels. A biodegradable soap is used.
Here's the tunnel washing crew in action at the transition road from northbound I-405 to northbound I-5:
