Accelerated Reconstruction of I-15 Devore Corridor

In 2004, the California Department of Transportation (Caltrans) applied an innovative, fast-track reconstruction approach to a heavily traveled highway rehabilitation project in the city of Devore. This article describes the project, in which a 4.5 km stretch of badly damaged concrete lanes was rebuilt in only two single-roadbed continuous closures totaling 210 hours. Counterflow traffic and 24-hour-per-day construction operations allowed Caltrans to cut the Devore project from 10 months to 19 days of construction. Analysis software incorporating traffic simulation models was used to arrive at an optimal and economical scenario for rehabilitation closures, a construction schedule and a traffic management plan. Other innovations adopted for this rapid rehabilitation project included a moveable barrier system; rapid strength concrete mix that made it possible to open up the road 12 hours after placement; incentive/disincentive provisions to encourage the contractor to complete the closures on time; a multifaceted outreach program to gain public support; automated work zone information systems to update travelers with real time travel information; and Web-based information systems for disseminating project updates and surveying public reaction.
