This design-build project called for the widening of 2.6 miles of Interstate 95 from six to ten lanes, and the reconstructing of four bridge structures. The PCL project team provided extensive reconfiguration of the on- and off-ramps during complete closures.
The client’s goals throughout this project were to increasing capacity and improve roadway geometry. By phasing construction, PCL maintained all existing lanes of traffic, increasing capacity as phases were complete. During design review of the final configuration, the project team commenced construction of the 22-foot-tall precast soundwalls at the right-of-way line, which minimized noise for residences along the 2.6-mile corridor. The client also recognized that closing on- and off-ramps for long periods would impact businesses and the traveling public, and so established a 30-day-per-ramp-closure rule. Through extensive planning efforts, the project team finished each ramp 10 days early, saving the public 70 days of inconvenience.
