Sewer Project Closes Lanes at Plano Parkway and Coit Road

Work on a major sewer capacity project at the Plano Parkway and Coit Road intersection began creating traffic disruptions on December 3. Crews reduced travel lanes and altered left turn lanes on West Plano Parkway to accommodate construction, and the temporary closures are scheduled to remain in place through December 19, weather permitting. Drivers in Collin County should expect altered left turn lanes and other traffic impacts while crews work in the corridor.

The lane restrictions are one element of a $16.1 million effort to increase sewer capacity across the area. Construction on the broader project began in July and is expected to continue through spring 2027. The long term timeline reflects a multi year investment intended to support ongoing and future development by increasing system capacity and reliability.

The immediate impact is on motorists and nearby businesses. Commuters will face changed turning patterns and potential delays during peak travel times. Local businesses near the intersection may experience changes in customer access while temporary traffic controls are in place. Emergency response routing and transit schedules can be affected by reduced lane capacity, making clear traffic management and timely communication important for public safety.

The cost and duration of the project underscore larger policy questions about how Collin County and municipal partners plan and pay for infrastructure to match rapid growth. The $16.1 million price tag signals a significant public investment in utility capacity, and the multi year construction window will require sustained oversight to minimize disruption and control costs.

Motorists should plan alternate routes where possible and allow extra travel time while work continues. Officials and contractors will need to maintain regular public updates so residents can track progress and anticipated impacts as the project proceeds toward its expected spring 2027 completion.
