In the coming months, the City of Casa Grande will be making changes to the lane layout of Trekell Rd at Florence Blvd. These changes are expected to reduce crashes, increase safety for cyclists, and protect pedestrians while improving traffic flow through the intersection.

The number of through lanes South of Florence Blvd. will be reduced from four lanes to two lanes with a center turn lane and bike lanes.  Trekell will not see an increase in traffic congestion. A traffic study showed that 4,481 vehicles traveled in both directions on Trekell over 24 hours. This volume of traffic makes four lanes are unnecessary for the volume of traffic at this intersection.

These alterations are called “road diets” and are primarily implemented on low-volume roadways to reduce crashes. The most common crashes on roads like Trekell result from cars slowing or stopping in through lanes with the intent to turn left. A driver blocking traffic in a through lane creates several opportunities for easily preventable crashes, such as read-ends and sideswipes.

Trekell sees significant use not just by motor vehicles but also by cyclists and pedestrians. The proposed changes will create bike lanes on either side of the road south of the Trekell-Florence intersection. Bike lanes make a safe route for cyclists without disrupting other travelers while also offering a buffer space between pedestrians and passing vehicles. Pedestrians will also benefit from reduced distance on lanes at crosswalks, which will be more visible to drivers.

This restriping project will start on April 9th in conjunction with a pavement preservation project in the same area.

We will add a dedicated right turn lane and convert a through lane to provide two left-turn lanes north of the intersection. To the south of the intersection, we will reduce the current layout of four undivided through lanes to one through lane in each direction, bike paths on the edge of the thru lanes, and a center two-way left-turn lane.

Construction of this project will begin in the fall of 2021.

Casa Grande is ever-evolving, and population growth projections promise significant change in the future. These will not be the last alterations needed, but they will provide a solid foundation for making our roadway network more efficient for drivers, cyclists, and pedestrians.
