Shrewsberry is providing civil engineering design services on the $1.17B Central 70 Public Private Partnership (P3) project for the Colorado Department of Transportation. This portion of the highway, between I-25 and Chambers Road, provides regional connection to Denver International Airport and 1,200 businesses that carries upwards of 200,000 vehicles per day. The project aims to upgrade the aging highway into the 21st century and rejoin communities that were divided by the existing viaduct. The project will reconstruct a 10-mile stretch of I-70, add one new express lane in each direction, restripe I-70 from I-25 to Brighton Boulevard to accommodate the additional express lane, remove the old viaduct, lower the interstate between Brighton and Colorado Boulevard, and place a 4-acre cover park over a portion of the lowered interstate.
The 4-acre community park over the I-70 is a defining feature of the lowered highway concept for I-70. The park will provide a vibrant ambient and activity opportunities like sports games, outdoor movies, concerts and farmers markets. Swansea Elementary School will have an area of the park for shared-use, but will be fully open to the public during all non-school hours and days.
The primary funding sources for the project includes Colorado Bridge Enterprise with $850M, Senate Bill 09-228 Funds with $180M, Denver Regional Council of Governments with $50M and the City of Denver with $37M.
Shrewsberry is providing design support services to the design team. Duties include interchange design, maintenance of traffic (MOT), sign design, and roadway design.
