The right-turn lane is expected to be closed for several months until early spring, according to the release.
Throughout the closure, two westbound lanes on RM 2222 will remain open. According to the release, one lane will be a dedicated left-turn lane onto southbound RM 620, while the other will allow drivers to turn left, continue straight or turn right.
The closure will allow TxDOT to complete the remaining work on RM 2222 as part of the area's bypass project.
According to the TxDOT website, this series of projects aims to add additional capacity to the congested roadway and reduce travel times through the corridor.
TxDOT held a ribbon-cutting ceremony in October marking the completion of the RM 2222 widening project. Additionally, the southbound lane of the new bypass road from RM 2222 to RM 620 is scheduled to open in April, after the northbound lane opened in summer 2021, according to a TxDOT spokesperson.
Construction on the bypass projects totals $27.2 million, with the city of Austin contributing $7.5 million from the 2016 voter-approved mobility bond.
