The Fort Bend Westpark Tollway expansion, currently under environmental review and design, will widen the existing two-lane, undivided road into a four-lane, divided highway. The project will extend the current four-lane controlled access tollway to the west from its current terminus at Grand Parkway/SH 99 through the FM 723/Spring Green intersection. In addition, one-way, two-lane frontage roads will be constructed both north and south of the Westpark Expansion and will not be tolled. The extended toll lanes will terminate and tie into the non-toll frontage roads west of the FM 723 intersection. From this point the four-lanes of divided frontage roads will continue west through the intersection of Westheimer Lakes North Drive and then taper into the existing two-lane road immediately east of the FM 1463/FM 359 intersection.
The current schedule is for design to be complete in 2015 with construction beginning in 2016. The duration of the construction phase is expected to take approximately 24-36 months.
