Yolo County, California Bridges: E50/Tower Bridge Gateway over US 50 and Jefferson Blvd

July 2013 (38.57667 Degrees, -121.52500 Degrees) 

Continuing north on Jefferson Blvd we arrived at the US50/Jefferson Blvd Interchange, that includes a long (1190 ft) connector ramp. The West Sacramento Off-Ramp (22-0129S) is a nine span steel stringer bridge that was built in 1966. This winding connector carries vehicles from the eastbound lanes of US-50 over Jefferson Blvd. and onto the Tower Bridge.

There are several interesting things about these connectors (besides how they can snake under and over freeways). Another interesting thing is how the lightweight steel superstructures are connected to the top of the concrete columns. Since the column reinforcement can't be developed into the superstructure, they must anchor the steel cross-braces into the columns.

Also, because the piers vary in height, most of the earthquake force will be carried by the shorter columns while the taller columns sway back and forth. Fortunately, there are no earthquake faults near West Sacramento.

Yolo County, California Bridges: Jefferson Blvd Bridges across the Sacramento River Deep Water Canal

May 2010 (38.561305 Degrees, -121.52829 Degrees) Jefferson Blvd Bridges

A little east of yesterday's Industrial Blvd Bridge and Overhead are the two Sacramento River Deep Water Canal Bridges (22C0168L/R). We previously studied these bridges back in 2010 when I was looking for movable bridges. However, the left bridge is a single span precast prestressed girder bridge that was built in 2005 and the right bridge (in the foreground) is a single span steel truss that was built in 1960 and improved in 2005. Apparently the movable bridge had been replaced since no ships travel through the east end of the canal (see Google earth photo below).

Yolo County, California Bridges: Industrial Blvd Bridge across the Deep Water Canal

July 2013 (38.56083 Degrees, -121.53889 Degrees) Industrial Blvd Bridge and Overhead

From the Elk Slough Bridge we drove north on Jefferson Blvd until we arrived at the Port of Sacramento and the Palmidessi (Industrial Blvd) Bridge and Overhead (22C0158). This is a four span cast-in-place prestressed concrete box girder bridge. It's 543 ft long, 72 ft wide, and it carries four traffic lanes. The bridge was built in 1997, it carries 5000 vehicles a day and has a sufficiency rating of 98.5. Under the bridge we can see some silos where rice is stored for shipment.
