This case study presents an innovative fast-track reconstruction approach as implemented in 2004 on the Interstate-15 (I-15) Devore Urban Highway Reconstruction Project in Southern California. The "Rapid Rehab" strategy was chosen for the Devore Project, in which concrete truck lanes were to be rebuilt along a 4.5-km (2.8-mi.) stretch of I-15 using two nine-days extended closures with 24/7 operations. In this "Rapid Rehab" strategy, state-of-practice technologies were adopted to accelerate construction, to mitigate traffic disruptions, and to propagate project information. From the initial planning and design stages, engineers used CA4PRS (Construction Analysis for Pavement Rehabilitation Strategies) software incorporated with traffic simulation models to arrive at an optimal and economical rehabilitation scenario. The postconstruction data validated the CA4PRS preconstruction analysis and simulation estimates of construction productivity and traffic delays. As a result of the implementation of an Automated Work Zone Information System (AWIS) and proactive public outreach, a 20 percent reduction in traffic demand through the Construction Work Zone (CWZ) was achieved, thereby reducing the maximum peak-hour delay to the "tolerable" level. Surveys on the project Web site showed public perception of the "Rapid Rehab" approach changed dramatically from initial reluctance to future support. Advantages of using this method of fast-track, accelerated highway reconstruction included less traffic disruption for the traveling public, longer pavement life expectancy(thirty-plus years), improved safety for motorists and workers, and reduced agency cost compared to the traditional approach using repeated nighttime closures.
