Published November 10, 2025. YUMA, Ariz. — A traffic improvement project is coming to central Yuma this month as crews prepare to install a traffic signal and new left turn lanes at the intersection of County 14th Street and Avenue 4E. The work will require Avenue 4E to be closed to through traffic in the area between County 13th Street and County 15th Street starting November 12 while crews complete the improvements.
The core elements of the project include the signal installation at the intersection and the addition of a left turn lane on each road leading into the crossing. Project leaders say the configuration is intended to improve traffic flow and reduce conflict points where turning traffic currently merges with through lanes. The closure of Avenue 4E is described as short term while crews carry out excavation, lane construction and signal equipment placement.
Motorists who normally use Avenue 4E through the 13th to 15th Street corridor should expect detours and intermittent lane closures in adjacent blocks. Local residents and commuters are encouraged to plan alternate routes in advance, allow extra travel time and exercise caution around work zones. Drivers should also be aware that lane shifts and temporary signage may change traffic patterns during the work window.
The project is likely to affect peak travel times for nearby neighborhoods, local businesses and school commuting routes. While the closure is limited to a specific block, even short term lane reductions can produce delays at adjacent intersections as motorists seek alternate ways through the area. Emergency response routing and delivery schedules may also be adjusted temporarily as crews complete construction.
Longer term, the new traffic signal and dedicated left turn lanes are expected to provide clearer traffic control at a busy local crossing, which can improve safety for drivers, cyclists and pedestrians and create more predictable traffic flow. Residents who use the intersection daily can look for updated signage and communications from county traffic authorities about the exact duration of closures and any required detours.
As work begins on November 12, local drivers are urged to heed posted signs and to plan for changes to their normal routes. County crews will be performing lane work and signal installation in the corridor, and officials recommend that drivers slow down in the area and follow directions to keep motorists and workers safe while improvements are under way.
