I-40 Colorado River Bridge Replacement

Colorado River Bridge Replacement

San Bernardino County, California

DISTRICT 8 SBD-40 PM 153.9 to 154.7

PN 0812000067/EA 08-0R380

Project Description

The California Department of Transportation (Caltrans) in cooperation with the Arizona Department of Transportation (ADOT) proposes to replace the Colorado River Bridge (California Bridge No. 54-0415, Arizona Bridge No. 957) spanning the California/Arizona state line on I-40 near Topock, Arizona. The purpose of the project is to improve the safety and integrity of the structure by addressing deck deterioration and strengthening the girders to increase the load rating. The safety of the traveling public will also be enhanced because standard lane and shoulder widths are proposed as well as an upgrade to the bridge rail system. There are three build alternatives in addition to the No-Build Alternative being evaluated. Alternative 1 (Existing Alignment) would construct a new bridge on the existing alignment, Alternative 2 (Northern Alignment) proposes to replace the bridge with an alignment to the north of the existing bridge, Alternative 3 (Southern Alignment) proposes to replace the bridge with an alignment to the south of the existing bridge, and Alternative 4 (No-Build Alternative).

Project Need

The purpose of the project is to improve the safety and integrity of the structure by addressing deck deterioration and strengthening the girders to increase the load rating. The safety of the traveling public will also be enhanced because standard lane and shoulder widths are proposed as well as an upgrade to the bridge rail system.

The project is needed as the concrete deck of the Colorado River Bridge has begun to deteriorate. There are spalls and delaminations along the outside shoulders, and transverse cracks throughout the transverse top mat rebar. The top mat transverse rebar are exposed and have inadequate concrete cover. If no rehabilitation is done, the existing deterioration will worsen and ultimately compromise the integrity and safety of the bridge structures.
