Lebanon Road is being widened from a four-lane roadway to a six-lane roadway to meet the growing demand of travelers.
The nearly $23 million project spans FM 423 to Todd Drive and will wrap construction late next year. Construction is actively underway, and officials are working at improving the existing lanes before adding to them, said Jason Brodigan, Frisco’s Engineering Services director.
Lebanon is slated to become a six-lane roadway, according to the city’s thoroughfare plan. Traffic growth and demand would be the driving factors behind activating the project now.
Other major thoroughfares in Frisco include Main Street, Eldorado Parkway and Custer Road, among others, according to the plan.
“We always knew [Lebanon Road] would be [six lanes]. It all fits into our overall plan of how we are going to move people,” Brodigan said.
A closer look
The number of drivers on Lebanon Road is increasing. In 2022 there were nearly 30,000 drivers on the road, which increased to about 33,000 drivers in 2025, according to Frisco’s traffic volume map. This number is the threshold that Brodigan said indicates an expansion.
“What we’re watching for is the amount of traffic, and once it reaches a certain threshold, it’s time to look at widening it,” he said.
Officials have identified a 10% increase in traffic volume but only a 3% increase in commute time on Lebanon. Brodigan’s team tries to minimize the effects of traffic on travel times, he said. In Frisco, Lebanon is about “middle of the road” in terms of traffic, he said. Other streets, like FM 423 and Custer Road, will see more drivers, but Lebanon is busier than roads such as PGA Parkway and Panther Creek Parkway, for example.
Some context
Funding for the $23 million project comes from city bonds and from Denton County. Within the county, the $7.5 million for the project is coming from its 2022 bond. Frisco will fund the remaining estimated $15.5 million through past bonds.
Because Frisco identified Lebanon Road as one of its top infrastructure priorities, the two local governments agreed to share the costs, Denton County Commissioner Ryan Williams said.
"We’re behind the eight ball when it comes to infrastructure ahead of all the development that’s going on and all the people that are moving here,” he said.
The bottom line
In Denton County, the population has grown over 38% from 2014 to 2024, according to U.S. Census Bureau data. Frisco has grown between 5% and 7% annually during that same time.
“We have so many people moving to Denton County, and they don’t get to bring their roads with them,” Williams said.
Because of the growth in Frisco, Brodigan said his department never runs out of things to do because roads are always needing to be updated or expanded.
The Lebanon project will be completed in three phases, though specific timelines for each phase are not available, Brodigan said.
“[Lebanon] had started to reach the traffic thresholds that we look for to widen to six lanes, and it’s also an older road that showed some signs of needing reinvestment, so the two things combined is why now,” Brodigan said. “We’re trying to get a little bit more reliable commutes for everyone.”
The new lanes will be added by using the space from the median instead of adding lanes to the outside portion of the road, Brodigan said. When Lebanon was first constructed, a larger median was made with the intention of cutting into it to widen the roadway.
“We cannot continue to build. There’s not a lot of thoroughfares left that need to be widened to six lanes," Brodigan said. "So, we’re going to have to be smart about how we move people."
