Opened for service when Ford’s Model T was considered a technical marvel, Caltrans is prepping a replacement for a century-old bridge still carrying traffic on what’s now State Route 99. 

“Originally constructed in 1918, it was widened sometime after that. It’s just met its useful life at this point, and time to be replaced.” Caltrans Project Manager Michael Webb said.

The short, simple span, widened in 1952, crosses Champlin Slough about three miles south of Los Molinos. 

Webb said water flowing beneath has taken its toll on the structure’s footings. 

At an open house tomorrow, locals can offer feedback. The $4.4 million dollar project won’t break ground until 2022. Webb estimates drivers can expect a two to three month detour.

Through traffic would be routed via Interstate 5, causing little delay. The same can’t be said for those in the immediate vicinity.

“That Vina to Los Molinos trip, we anticipate that (adding) 10 to 15 minutes.” Webb explained. 

To reduce costs, officials ruled out a temporary bridge. A new alignment was also nixed Webb said it would add accident causing curves.  

Tomorrow’s open house runs from 4 to 7 p.m. at the Tehama County Veterans Memorial Building in Los Molinos.
