How and Where Can I Access the Express Lanes?

For an Express Lane to function safely and effectively in a heavily congested corridor like MoPac, access to and from the Express Lane must be controlled or limited. If access is not restricted, traffic in the Express Lane can slow down or back up as drivers try to weave in and out of the lane.

To control access and separate the Express Lanes from the adjacent regular lanes, a buffer zone with flexible plastic sticks has been constructed. While drivers can only legally enter or exit the Express Lanes at designated locations, emergency vehicles can drive over the flexible sticks and access the lanes to remove disabled vehicles easily anywhere along the 11-mile route. Emergency responders can remove the delineators or direct motorists to drive over them if an incident occurs in the Express Lane and blocks traffic.

During development of the MoPac Improvement Project, the project team conducted traffic studies and developed traffic models to determine the best location for entry and exit points. It was determined there should only be three access points:

  • North: near Parmer Lane
  • Central: between Far West Boulevard and RM 2222
  • South: at Cesar Chavez Street and 5th Street

NORTH

  • Northbound: The Express Lane ends just south of the Parmer Lane exit allowing drivers to merge across traffic and exit at Parmer Lane or continue north on MoPac.
  • Southbound: The Express Lane begins just south of the Parmer Lane overpass. Drivers heading south on Loop 1 Toll or entering MoPac from the Scofield Ridge Parkway entrance are able to access the Express Lane at that point. Drivers entering MoPac southbound at Parmer Lane are not able to access the Express Lane until the Central access point south of Far West Boulevard. However, Parmer Lane drivers can choose to go north on the MoPac frontage road, do a u-turn at Scofield Ridge Parkway and then enter MoPac to access the Express Lane.

CENTRAL

  • Northbound: Just north of RM 2222 there is a break in the plastic poles and an auxiliary lane on the left side of the road that allows traffic heading north in the Express Lane to safely merge into the regular lanes and then exit to Far West Boulevard and other exits north of that point including US 183. Meanwhile, traffic coming north on MoPac is able to merge into the Express Lane just north of RM 2222. Drivers entering here must stay in the Express Lane until they reach the Parmer Lane exit.
  • Southbound: Just south of Far West Boulevard there is a break in the plastic delineator poles and an auxiliary lane on the left side of the road that allows traffic heading south in the Express Lane to safely merge into the regular lanes and then exit to RM 2222 and other exits south of that point. Meanwhile, traffic coming south on MoPac from US 183 and other points along MoPac are able to use the auxiliary lane to merge into the Express Lane. Drivers entering here must stay in the Express Lane until they reach Cesar Chavez Street and Lady Bird Lake.

SOUTH

  • Northbound: Drivers heading north on MoPac are able to enter the Express Lane on the north side of Lady Bird Lake. Drivers heading out of downtown Austin are able to enter the northbound Express Lane directly from Cesar Chavez Street via a special entrance ramp.
  • Southbound: Drivers heading south in the Express Lane have the option to exit directly to Cesar Chavez Street and 5th Street via a special exit ramp or they can continue south where the Express Lane joins the existing lanes. An environmental study is underway to look at the mobility needs on the MoPac corridor from Cesar Chavez Street south to Slaughter Lane (please visit www.MoPacSouth.com).
