I-64 Capacity Improvements Segment I
In March 2015, the Virginia Department of Transportation awarded Shirley Contracting Company LLC, (Shirley) the Interstate 64 Capacity Improvements -Segment I Design-Build contract. The project entailed the median widening of approximately 5.2 miles of I-64 in Newport News, VA; adding a new travel lane and full width shoulder in each direction on the interstate; replacement or widening of six bridges, including two bridges over CSXT Rail; and construction of nearly 2.5 miles of noise barrier wall.
Utilizing our experiences working on similar interstate facilities, the Design Team developed an innovative Temporary Traffic Control (TTC) approach that allowed commencement of construction activities within six months of NTP by creating an Advanced TTC Plan Set. This strategy allowed for shoulder strengthening and median clearing within existing right-of-way to start while final roadway and bridge design elements were being completed. The Environmental Team worked closely with the permitting agencies to avoid work in jurisdictional areas while the final Joint Permit Application and mitigation measures were finalized.
Although the RFP allowed for the widening and rehabilitation of the existing bridges over Industrial Park Drive and CSX Railroad, our Team developed plans which provided two new 2-span bridges in lieu of widening and repair of the existing 3-span bridges, resulting in shorter structures which will require less maintenance by VDOT.
Additional project elements included; widening and repairs of 4 existing bridges; extensive maintenance of traffic operations for over 100,000 VPD; TMS, DMS, CCTV and overhead signage/installation; installation of 7 bio-retention and constructed wetland SWM facilities; utility relocation/installation; installation of over 210,000 S.F. of Noise Barrier Wall; and, installation of over 15,000 LF of storm sewer including trenchless crossing.
As the Design-Builder and Lead Contractor, Shirley was responsible for management and oversight of the entire Project, including design and engineering, environmental permitting, utility relocations and overall Project administration and construction management, including 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 responsible for creating and monitoring the schedule throughout design and construction.
The Project received the Design-Build Institute of America’s National and Mid-Atlantic Region Award of Merit recognizing the high quality and adherence to the Design-Build Project Delivery standards.
