The three overpasses on I-215 from Washington Street in Colton to Barton Road in Grand Terrace are hit by oversized loads more often than any other freeway bridges in the Inland area. They account for seven of the 10 such hits in the Inland area in the past year, according to Caltrans data.
The bridges, each less than 15 feet above the 215, are between Interstate 10 and highways 60 and 91. The busy route sees more than 12,000 trucks each way daily. Oversized loads — those that top out at 14 feet or taller — hit the bridges unless the truckers detour off the interstate, following specific routes listed on Caltrans and city-issued special load permits.
In some cases, the load hits two or three bridges in a row — Barton Road, Newport Avenue and Washington Street. Trucks northbound on I-215 have clipped the Washington Street overpass four times since Jan. 30, and seven times in the past two years. And that’s just the strikes that are reported.
