Lehman Road Construction Update

Updated Aug. 6, 2020.

Lehman Road is open for traffic from Ranch to Market Road 150 to Bunton Creek Road. Contractors still need to place illumination poles north of Hallie, complete striping and a few areas throughout project will still need to pour small amounts of concrete.

Lehman Rd. Highlights

Dedicated left-turn lanes at cross streets
Increase Intersection capacity at Bunton Creek Rd. & FM 150
Low water crossings improved at Plum Creek and Prairie on the Creek
Storm system designed to carry 25 year storm event (Existing ditch and structures system convey less than 5 year storm event)
Upgrade of 18" wastewater line north of RR 150 to align with 24" from Southside Interceptor Project
Installation of 30” wastewater line and 12” reclaim water line from north of RR 150 (and connection to Southside Interceptor line) to City Park property.
