A new project intended to deal with what’s been a decades old problem at a Highway 101 underpass on the South Coast is complete.
The Highway 101 undercrossing at Castillo Street has had issues for years, because of underground water which would continually damage the roadway. Water in the undercrossing due to the seepage would also create safety concerns.
Today, Caltrans announced a $1.5 million dollar project to repair the damage is complete. The two month project included the installation of a concrete slab over a geothermal membrane which directs underground water towards a drainage system.
