W. 11th Street Bridge Replacement Project
The W. 11th Street Bridge has a Sufficiency Rating of 13.1, which is one of the lowest rated bridges in the entire state of Colorado. It is the only load restricted (19 Tons) bridge within the City limits of Pueblo
The existing bridge is located immediately adjacent, and is attached to, the railroad bridge that spans the Wild Horse drainage, approximately ½ mile north of the confluence of Wild Horse Creek and the Arkansas River. The existing bridge was constructed in 1925 to replace the bridge that was destroyed by the 1921 Flood.
In the fall of 2007 the Public Works Engineering Department applied for and received a bridge replacement grant for the W. 11th Street Bridge from the Federal Highway Administration. The grant had a 20% Local Agency match but because of the start of the recession, there were no funds available for the match and therefore the Public Works Department was unable to request that the Council accept the grant. Since then, the Colorado Legislature passed the Funding Advancements for Surface Transportation and Economic Recovery (FASTER Bill) that increased vehicle registration fees for much needed roadway and bridge improvements statewide. A second grant was also received and the required match funds were committed.
Although the existing bridge currently has a very low Average Daily Traffic (ADT) of approximately 500 vehicles per day, the new bridge will serve as an important piece of a future west corridor link connecting the downtown area to Pueblo Boulevard and eventually directly to Pueblo West when Joe Martinez Blvd. is completed, which is part of the 2035 Long Range Transportation Plan.
The engineering consulting firm AECOM (formerly URS) was hired to perform the design and to assist the City with the environmental and other regulatory approvals necessary. The design and approval process was completed late in the summer of 2016. During the initial stages of the design phase, the design team considered three options for the location of the new bridge. It was decided to locate the new bridge in the alignment of W. 11th Street.
Lawrence Construction Company (Littleton, CO) was the low bidder for the bridge replacement project ($ 4,496,065).
The existing bridge will remain in place due to its potential historic value.
UPDATE: Detour for the remainder of the Construction Phase to go into effect May 24th, 2017
