I-66 Widening

In August 2013, the Virginia Department of Transportation (VDOT) awarded Shirley Contracting Company LLC, (Shirley) the Interstate 66 (I-66) Widening Design-Build contract. Our Team was chosen in large part because of our significant experience associated with construction of complex transportation projects on high volume, high speed roadways, excellent safety record, partnering approach, and abilities to work with adjacent concurrent construction under separate contracts. The Project entailed the widening of approximately 2.5-miles of I-66 in Gainesville, Virginia in each direction, replacement of two secondary overpass bridges, extensive maintenance of traffic operations for over 100,000 VPD, construction of 250,000 SF of noise barrier wall, construction and integration of an extensive Intelligent Transportation System consisting of cameras, detectors, digital message signs all running off a new fiber communication network, roadway lighting, utility relocation/installation, and traffic detours.

As the Design-Builder and Lead Contractor, Shirley was responsible for management and oversight of construction, including design and engineering, utility relocations, public outreach, overall Project administration and construction management, and QA/QC. All construction work was performed on a heavily traveled roadway and all lane restrictions were coordinated by Shirley with VDOT to allow for public notifications of impacts to traffic. Shirley was the primary point of contact with the Owner in public relations and getting notices out to traveling motorists, businesses, home-owners and local politicians. Shirley was also responsible for creating and monitoring the schedule throughout design and construction.

Utilizing our previous experience working on I-66 and similar facilities, Shirley was able to sequence work operations and phase the construction operations to minimize impacts to the traveling public. Much of the phased construction took place behind temporary barrier keeping both the workers and the public safe during construction. In addition, the Team was able to maximize the existing alignment of I-66 with minimal additional efforts so that a paved shoulder was maintained in almost all areas of the Project.
