McKinney is ready to start detailed design on extending Stonebridge Drive north from US 380 to Bloomdale Road, a project city engineers estimate will cost about $24 million to build.
A consent item on the City Council's Tuesday, Nov. 17, agenda would hire Kimley-Horn and Associates for $3,438,500 to engineer the road, with authority to spend up to $3.8 million if the scope shifts. The same firm completed an alignment study for the corridor under a contract the council approved March 3.
The city's Master Thoroughfare Plan calls for this stretch of Stonebridge to become a four-lane greenway arterial. According to the staff report, the design will cover:
- the two northbound lanes from US 380 to Bloomdale Road, plus a full build-out of the Stonebridge intersection at US 380
- a sidewalk along the entire length
- two multi-span bridges, carrying three lanes over Wilson Creek, designed with what staff calls signature bridge aesthetics and their own lighting
- underground storm sewers, traffic signals and street lighting
- roundabout design, a flood map revision and a study of the Wilson Creek watershed to size the crossing
Staff put the preliminary construction estimate at $23,963,000. Design is expected to take about 15 months, with construction anticipated to begin in 2028. The city expects to pay for construction with street bonds issued in its 2027 and 2028 budget years, the report says. After this contract, about $3.18 million would remain in the project's budget.
Repairing a sewer line exposed by erosion
Another consent item on the same agenda addresses a 27-inch wastewater line that crosses Stover Creek about 600 yards northwest of County Roads 124 and 161. Inspections found roughly 200 feet of the line exposed above the creek and vulnerable to the weather because of erosion, according to the staff report.
