The New Mexico Department of Transportation (NMDOT), in cooperation with the Federal Highway Administration, is conducting a study for I-40 Bridges over the Tijeras Arroyo near the 1-40 Interchange with NM Highway 333. We hosted an in-person public meeting to present the recommended improvements and receive public input before finalizing the recommendations.
In the study area, there are four bridges spanning the Tijeras Arroyo that were built in 1978 when I-40 was constructed. The purpose of this study was to evaluate the condition of the existing bridges and to develop recommendations to address physical deficiencies. Based on the data collected, the condition of the bridges ranges from satisfactory to poor. The preliminary recommendations include:
Closure/removal of westbound off-ramp bridge – this bridge is in fair condition; however, expensive repairs would be needed to extend its service life a few more years. Even when factoring in the benefits the bridge provides to the community, the cost of rehabilitation or replacement exceeds the cost of permanently closing the bridge.
Replacement of I-40 westbound and eastbound bridges – these bridges have significant deterioration requiring expensive repairs to extend their service life a few more years; therefore, bridge replacement is the preferred option.
Rehabilitation of south frontage road bridge – this bridge is in satisfactory condition and can remain in service with minor repairs and maintenance.
The comment period has ended. We greatly appreciate all of the input shared. It will help our team make a more informed decision and design improvements moving forward.
