5400 South Flex Lanes, Redwood Road to Bangerter Highway

Flex Lanes Overview

UDOT will implement Utah's first Flex Lanes project on 5400 South between Redwood Road and Bangerter Highway in summer 2012. By switching the direction of traffic on one or more lanes, UDOT can improve traffic flow in the peak direction using the existing roadway.

Flex Lanes are an effective way to increase traffic flow using the existing roadway width. They are most effectively used on roadways with traffic congestion primarily in one direction during peak travel times. Many corridors and freeways throughout the country successfully use flex lanes (also called reversible lanes) to reduce traffic congestion.

The increasing traffic volume, single-direction congestion during peak hours and long commutes make Flex Lanes on 5400 South an ideal solution. Implementing Flex Lanes will

• Improve travel time and reduce traffic congestion now and in the future
• Increase peak-hour roadway capacity without the need to widen the roadway and impact existing property
• Provide a cost effective way to make what we have work better

UDOT has studied the use of Flex Lanes and designed a series of operational features to ensure safety and effectiveness at 5400 South:

1. Flex Lanes will operate during the morning and evening commutes and other peak traffic hours. The specific hours of operation have not been determined yet.
2. Electronic overhead lane control signs will be placed approximately every 500 feet to direct traffic. Frequent electronic signage will ensure a safe Flex Lanes system.
3. A center lane will be maintained for left-hand turns. To increase safety left turns exiting driveways are restricted while Flex Lanes are in operation, except at signalized intersections.
