Frisco Street and Cobb Hill Drive Intersection Closes Monday for Seven-Month Roundabout Construction

Major Intersection Closure Begins Monday

Frisco residents should prepare for significant traffic disruptions beginning this week. [1] The intersection of Frisco Street and Cobb Hill Drive will close for about seven months starting Monday, October 12, as crews construct a roundabout. [1] The roads leading to the intersection will close at 9 a.m. and are expected to remain closed until late in the construction period.

This extended closure represents a substantial infrastructure project that will reshape traffic flow in the area for many months. Residents who regularly use this intersection for commuting, school drop-offs, or other daily activities should begin adjusting their routes immediately to avoid delays and confusion once the closure takes effect.

Impact on Memorial High School Access

[1] The closure will require many parents and students to use alternate routes to and from Memorial High School after Fall Break. This timing is particularly important as families return to their normal school schedules following the break period. School-related traffic represents a significant portion of daily vehicle movements in the area, making this transition especially critical for planning purposes.

[1] As shown on the attached map, the northernmost school driveway on Frisco Street will be closed during construction. [1] Vehicles will not be able to approach the school from the north. All traffic must enter from alternate directions, requiring drivers to significantly modify their usual routes.

Recommended Alternate Routes for School Access

To help navigate the intersection closure, the City of Frisco has provided guidance for drivers heading to Memorial High School. [1] Drivers coming from neighborhoods east of Preston Road should use Eldorado Parkway and turn north onto Frisco Street to reach Memorial High School. [1] They should use the same route when returning, ensuring a consistent approach for parents and students.

This recommended route allows traffic from eastern neighborhoods to bypass the closed intersection entirely while still accessing the school. Families should familiarize themselves with this alternate path before Monday to ensure smooth transitions during the construction period. The consistency of using the same route in both directions can help parents and students develop new travel habits quickly.

Planning Ahead for Construction Period

With the closure lasting approximately seven months, residents should plan for extended disruptions to their normal traffic patterns. The project's duration means that alternate routes will need to become habitual rather than temporary workarounds. Frisco families and commuters should take time this weekend to study the recommended routes and plan their travel schedules accordingly.

Those who use the Frisco Street and Cobb Hill Drive intersection regularly are encouraged to contact the City of Frisco for additional information or clarification regarding the closure. Official city resources, including detailed maps and traffic guidance, are available to help residents and workers navigate the construction period effectively. Planning ahead now can minimize frustration and delays once the closure begins Monday morning.

Additional Downtown Frisco Closure Information

In addition to the Frisco Street and Cobb Hill Drive intersection closure, Frisco residents should note another temporary traffic change downtown. [2] Main Street will be closed between 3rd Street and North County Road on Tuesday, October 13, for the Rail District Celebration in downtown Frisco. [2] The road will close at 1 p.m. for event setup. [2] The event begins at 6 p.m., and the road will reopen at 11 p.m.

[2] Additional public surface parking is available along Oak and Elm streets, providing options for those attending downtown events.
