The Fort Bend County Toll Road Authority will begin construction on an extension of the Fort Bend Parkway Toll Road from Sienna Parkway to Sienna Ranch Road following the project’s approval at a Fort Bend County Commissioners Court meeting Aug. 24.

The extension will be located in Missouri City, south of Sienna Springs Drive near Pecan Estates, according to FBCTRA officials.

The new section of road will be located on land predesignated for the extension, as it was planned before any houses were built, said Gary Gehbauer, director of program management for BGE Inc., an engineering firm working on the project.

Design work for the project began in 2019, according to the FBCTRA. Construction is expected to begin in mid-September and is projected to be completed by late 2022 or early 2023.

According to the FBCTRA, the extension will be four lanes and include a northbound exit ramp and a southbound entrance ramp at Sienna Parkway. It will also include a northbound entrance ramp, a southbound exit ramp and a traffic signal at Sienna Ranch Road.

The budget for the extension’s construction and design is $43.3 million, officials with the FBCTRA said. Funding for the project comes from toll revenue, Gehbauer said.The segment is part of a larger project to extend the Fort Bend Parkway Toll Road from where it begins, at Hwy. 90 and Chimney Rock Road, across the Brazos River to FM 2759 and up to the Fort Bend Grand Parkway Toll Road.

There is no specific timeline for the remaining phases of the project, however, the design of the extension to FM 2759 is expected to cost $20.5 million.
