Two long-term projects that will greatly expand FM 423 are in the works.
The first project from just south of Eldorado Parkway to US 380 will widen the road from two lanes to a six-lane divided roadway.
The 3.48-mile project began in October with temporary pavement for culvert work, temporary signals, excavation and embankment work, said Michelle Releford, spokesperson for the Texas Department of Transportation.
Heavy machinery and dirt work can be seen along the section.
The expansion project will cost about $29.8 million and is expected to be mostly complete by July 2018, Releford said.
The second FM 423 project runs through The Colony and is a 7.5-mile stretch from SH 121 to Stewarts Creek Road, which is just north of Eastvale Park.
The project will widen the existing four-lane road to eight lanes from
SH 121 to Cougar Alley and to six lanes from Cougar Alley to Stewarts Creek Road.
Widening work includes waterline placement, temporary signals and temporary pavement, excavation and embankment work.
The construction project, which also began in October, will cost $57.9 million and is expected to be mostly complete by October 2017,
East Main Street
Construction continues on East Main Street from Preston Road to Custer Road.
The project to replace the two-lane road with a six-lane, divided roadway began in June 2013 and is now about 60 percent complete.
Traffic has continued to flow throughout the construction process, with construction officials shifting open lanes as the road progresses through different phases.
Construction is expected to be complete by September.
The Texas Department of Transportation is funding $27 million of the project.
The city of Frisco is participating with about $2.75 million.
Roundabout at Ohio Drive and Warren Parkway
A roundabout—the first in Frisco—is still expected to be constructed at the intersection of Warren Parkway and Ohio Drive.
The roundabout will replace the existing four-way stop.
The city-funded $365,000 project is about halfway through the design process and construction is expected to begin by March 2015.
Plans for a multilane roundabout have been in the works for years.
Three areas along Ohio Drive have been identified by city traffic officials as ideal options for roundabouts—Warren Parkway, Gaylord Parkway and Prestmont Place. Following feedback from concerned residents about the possible roundabouts, the Frisco City Council decided to start by constructing one roundabout before moving forward with the other two.
Roundabouts are seen as an alternative to a four-way stop because they are designed to allow cars to slow instead of stop and cause less delay.
After months of construction, work on the portion of Stonebrook Parkway that will connect the road from Fighting Eagles Lane to Longhorn Trail is getting close to completion.
The new six-lane, divided concrete roadway project includes an underpass beneath the BNSF Railroad tracks.
City engineering officials said the project is about 80 percent complete and expected to be complete no later than June.
The $15.75 million project is being funded by the city of Frisco ($6.15 million) and the Texas Department of Transportation and the North Central Texas Council of Governments ($9.6 million).
When finished Stonebrook Parkway will have a connection from FM 423 through the Dallas North Tollway and Preston Road, where it becomes Rolater Road.
The project also includes drainage and water and wastewater infrastructure.
