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 Las Vegas Boulevard, was constructed in 1968. The I-947 structure, the bridge over Las Vegas Blvd and extending south to Bruce, was constructed in the 1980s. 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.
Project Goals
NDOT’s goals for this project include:
- Improving safety and operations
- Improving downtown access
- Addressing aging infrastructure
- Extending High Occupancy Vehicle (HOV) network to downtown along I-515
Proposed Improvements
Long-term improvements proposed as part of this project include:
- Replacing or removing the 1.6-mile viaduct
- Fixing on and off ramps located too close together
- Adding freeway capacity
- Adding new HOV interchanges at City Pkwy and Maryland Pkwy
- Braiding ramps to/from I-15 and I-515
