Frisco widens Lebanon Road to six lanes as traffic surges

Drivers on Lebanon Road are already feeling the squeeze: lane shifts, bridge repairs and months of construction on a corridor Frisco says has outgrown its four lanes. The city’s nearly $23 million widening is intended to make the route easier to use between FM 423 and Todd Drive, but the tradeoff for now is more work zones before any relief arrives.

Frisco is rebuilding Lebanon Road as a six-lane divided roadway in one of the city’s fastest-growing areas, just short of Legacy Drive. City officials said the project was awarded by City Council in October 2025, construction began in December 2025 and completion is now expected in the fourth quarter of 2027. The widening includes pavement reconstruction, bridge work, drainage improvements, median landscaping and irrigation, pavement markings and signage, street light replacement, turn-lane improvements and streambank mitigation on Stewart Creek.

Engineering Services Director Jason Brodigan said the city had long expected Lebanon Road to become a six-lane roadway under the thoroughfare plan, adopted in April 2025, but traffic has now pushed the corridor past the point where expansion is necessary. Traffic counts rose from nearly 30,000 drivers in 2022 to about 33,000 in 2025, a jump of roughly 10%. During that same period, commute time increased only 3%, a sign the road is still functioning but under growing pressure.

That pressure is most visible at Lebanon Road and FM 423, which Frisco’s intersection-improvement program identified as one of the city’s highest-volume intersections. The city previously widened capacity at seven of its busiest intersections, and Lebanon Road is now part of that same effort to stay ahead of congestion before daily backups become routine.

The widening is being built in three phases, including work at Teel Parkway and Lebanon Road, a left-turn lane into the Sonic Drive-In east of Todd Drive and interior lanes on Lebanon Road. Frisco also said turn-lane improvements are planned at Lone Star Ranch Parkway, Teel Parkway and Rock Creek Parkway. A separate traffic notice issued April 17 said lane shifts between 4th Army Drive and Quail Hollow Road began April 20 to support Stewart Creek bridge repairs, with westbound traffic moving to the south half of the roadway for about two months.

For nearby neighborhoods, businesses and commuters, the payoff should be a wider corridor with better flow once the work is done. Until then, Lebanon Road is one more reminder that Frisco’s growth is still outrunning its roads, even as the city tries to widen them before the gridlock takes over.
