Downtown Access Project Logo

Project Overview

The Downtown Access Project is located along I-515/US-95 from Mojave Road to Rancho Drive. In preparation of compliance with the National Environmental Policy Act of 1969 (NEPA), NDOT is beginning to prepare environmental and preliminary engineering studies for the project.

Project Need

Within a large portion of this corridor, I-515 is on a viaduct that consists of two bridges. The G-947 bridge, from the UPRR crossing to 8th Street, was constructed in 1968. The I-947 bridge, from 8th Street to Bruce Street, was constructed in 1980. As these bridges continue to age, they require costly maintenance repairs to keep them in service. Preliminary design alternatives will be developed to determine appropriate measures to reconstruct the freeway in this area to address the aging infrastructure, accommodate future travel demands, improve safety, and travel time reliability.

 

G-947 built in 1968 (52 years service life). I-947 built in 1980 (40 years service life).
