The I-70/Havana interchange is a critical part of the I-70 corridor and provides access to commercial, light industrial businesses, local residents in Stapleton, the Denver jail, and CDOT maintenance yard. I-70 carries over 190,000 AADT in the area and is the primary backbone of east-west travel through the area. The primary purpose of this project is to replace the bridge on I-70 over Havana Street and the Union Pacific Railroad spur and resurface I-70 from the east side of Pena Boulevard to I-225. The existing bridge has reached the end of its service life and is in need of replacement as quickly as possible.
Through innovative design and partnering with CDOT and the City of Denver, Lawrence Construction and Mortenson were able to design and build the project well under the project budget and with minimum impacts to the traveling public. The old bridge was replaced by a two span 153’ bridge that allowed for the additional height requirements of the UP. A second railroad tunnel was built to the east of Havana Street to accommodate future expansion of the UP.
The use of precise design allowed for minimal phasing and earthwork creating a safe project with minimal traffic shifts. This allowed for safer travel for the traveling public and all personnel. ATC’s were used for the bridge design allowing for less earthwork on the project reducing cost to the project and overall scope.
