Transportation

This project provided grade-separated vehicular access to all facilities south of Harry Bridges Boulevard from a heavily utilized rail line. The grade separation project eliminates the conflict between vehicular traffic and two existing at-grade rail crossings. It will provide unimpeded grade-separated vehicular access to the South Wilmington area, which is made up of many businesses, and community areas. IEM provided cost estimating, scheduling, and document control services for this project.

This project added an additional lane from the SR-47 connector to the Northbound I-110 and extended the existing off-ramp at John S. Gibson Blvd. The off-ramp was modified to become a two-lane exit to accommodate one shared through- and left-turn lane and one exclusive right lane and lengthen the existing off-ramp. An additional left turn lane will be added to Southbound John S. Gibson Blvd. for traffic destined to Port terminals. This additional lane will continue to the John S Gibson off-ramp with two lanes from the existing one lane, thus improving the intersection capacity with an overall improved level of service. IEM provided construction management services for this project.
