Pflugerville (Travis County)–Engineering is underway on planned improvements to the intersection of Farm-to-Market Roads 685 and 1825, where upgrades include a displaced left turn lane and traffic signal timing changes.
Pflugerville City Council on April 28 approved a agreement with the Texas Department of Transportation (TxDOT) regarding the intersection where a displaced left-turn lane will make a continuous-flow intersection.

Here, motorists wanting to turn left will cross before they enter the intersection.
A left-turn signal in the intersection will no longer be necessary, and vehicles traveling in both directions can proceed, including those going past the intersection and those turning right or left.
Within the city of Pflugerville, FM 685 is also known as Dessau Road, and FM 1825 is known as Pecan Street.
Dallas-based Pacheco Koch Consulting Engineers is working on the Pflugerville project design, which is tentatively scheduled for completion in mid-August.
The city and TxDOT estimate that the construction phase of the project will go to bid Oct. 5 with a bid opening scheduled for Nov. 13.
A contract could be awarded no later than Nov. 27, and construction could take place between the end of November and mid-May 2021, according to project documents.
There is presently no preliminary construction cost estimate. VBX members may track this project using ID number: 2020-37EC.
The continuous-flow intersection remains an infrequently used road design in the United States. San Antonio and San Marcos are the only two Texas communities to have a displaced left-turn configuration.
TxDOT rebuilt the Bandera Road/Loop 1604 intersection with displaced left-turn lanes in 2019. TxDOT similarly reconfigured two intersections of Interstate 35 in San Marcos.

City Council last January approved a $416,000 supplemental agreement with Pacheco Koch, expanding the engineering firm’s scope of work to account for the estimated traffic impact from Project Charm, which will be located on East Pecan near Texas 130.
