SINGLE-POINT URBAN INTERCHANGES

Locations

The new interchanges at SH-41 (under construction), Northwest Boulevard, and US-95 will be single-point urban interchanges (SPUIs). The existing interchanges are
diamond interchanges and will not meet future travel demands.

Benefits
  • Improve efficiency and increase capacity by 25% more than diamond interchanges

  • Meet travel demands beyond the design year 2045 in conjunction with local road
    intersection improvements

  • Reduce traffic signal cycles and delays by allowing all left-turn movements to be
    controlled by a single signal

  • Decrease points of traffic conflict
