State may tear down major Sacramento bridges to build bigger ones for megatrucks

Flush with new gas tax funds, state officials are exploring what could be the biggest Sacramento freeway redo in modern times — tearing down and replacing the twin freeway bridges that carry Interstate 5 over the American River.

Caltrans says the half-mile spans just north of downtown are among 45 pinch-points the agency has identified on three major freight corridors — I-5, I-580, I-10/60 — that force oversized trucks onto sometimes long and costly detours.

In some cases, overpasses are too low. A notorious one on I-80 in Berkeley less than 5 miles from the Oakland port is only 14 feet, 9 inches tall, more than a foot lower than the 16-foot modern federal standard for existing bridges. Federal standards for new bridges are 16 feet, 6 inches.

... Some heavy trucks, typically more than 80,000 pounds, will take a 51-mile detour by exiting I-5 at Florin Road or farther south. From there, they work their way over to Sunrise Boulevard, then use Greenback Lane and Elkhorn Boulevard and finally loop back to Highway 99 to rejoin I-5 near the airport.

Don't know enough about Sacramento but I'm guessing this project would move faster than the "proposed"  new Bay Area bridge?

Would it be possible to give trucks their own lanes on the bridge and its approaches? And build the overpasses high enough (or lower the roadway) for even oversized trucks to fit through?

Does anyone know where this bridge is?

Interchange at Berkeley Marina is marked 14'5" coming from the south, and 14'4" coming from the north.

5 miles from part of the port in Oakland is about the northern I-80/I-580 split (I-80 is the top level). One of the ramps at the CA-13 interchange has a marked clearance of 15'1"; another is marked 15'2". Haven't found a bridge marked 14'9" yet.
