ACT is pleased to announce the completion of construction of the I-10/Alabama Street Improvement Project in Redlands, California. The project improvements were delivered to address several concerns at the I-10/Alabama Street interchange. Vehicle queues at off-ramps and overall traffic volumes are projected to significantly increase, resulting in unacceptable levels of service by 2042 unless improvements are constructed.nnThe project has addressed these concerns by constructing widened off-ramps in both directions of I-10 and widening Alabama Street to implement turn pockets serving both interchange on-ramps. Additional improvements included upgraded pedestrian facilities to comply with the Americans with Disabilities Act, 4-ft bicycle lanes, and several new retaining walls.nnOur firm served as the prime consultant for the Project Study Report-Project Development Support (PSR-PDS), Project Approval/Environmental Document (PA/ED), and Plans, Specifications and Estimate (PS&E) phases of the project, then provided design support services throughout the construction phase. During all four phases, ACT worked closely with SBCTA, Caltrans, and the City of Redlands to deliver the improvements as expeditiously as possible, on schedule, within budget, and with very few changes during the construction phase. The PSR-PDS was approved two months ahead of schedule by working closely with Caltrans to obtain early buy-in on the design concepts. Additionally, the ACT team overlapped the PA/ED and PS&E phases by submitting the PA/ED-phase plans as the Geometric Approval Drawings shortly after the Project Report was signed. This approach allowed the PS&E phase to begin the same month that the PA/ED phase concluded.nnACT is proud to have successfully delivered the I-10/Alabama Street interchange improvements as a community-needed project. Ultimately, ACT was successful in delivering the project with no impact to right-of-way or utilities.
