Actual construction of the roadway is expected to begin in 2019, but the city is taking steps to explore all possible alternatives to improve the roadway, said Brian Moen, Frisco’s assistant director of transportation.
The design phase for Legacy Drive began toward the end of 2016, and in February 2017, the city started a more in-depth traffic analysis for future alternatives, Moen said.
“Right now, the pavement of the roadway is in poor condition, and much of it needs to be reconstructed. It’s one of the oldest roads we have in town,” Moen said.
Completed work includes field surveying, subsurface utility investigation, geotechnical investigation, and collection of traffic counts and travel times, Moen said.
The city is working to develop a traffic simulation model, which is a computer-based program that predicts the response of a roadway to traffic demands.
Moen said the traffic simulation program will be used to evaluate three alternatives to improve Legacy Drive.
Officials in the city’s engineering department have met with neighborhoods that could be affected by roadway improvements.
“We’ve had ongoing meetings with [Stonebriar Legacy Association of Neighborhoods] ... and when we reach different milestones in the study, we’ll get back together and provide updates,” Moen said.
Frisco is using an interlocal agreement with Plano to make improvements to the SH 121 and Legacy Drive interchange. Improvements to the interchange are expected to be done by the end of 2018, Moen said.
