Northbound MoPac Aux lane between 35th and 45th Streets to close for 6 months
There will be a significant traffic change starting the weekend of April 8th.
The MoPac Improvement Project will need to close a portion of the auxiliary
lane on northbound MoPac between the 35th Street entrance ramp and the 45th
Street exit ramp. The closure will be in place for approximately 6 months
to allow the workers to remove a now abandoned City of Austin water line,
to build a retaining wall/sound wall, and to widen MoPac in the area.
Drivers will still be able to use both the 35th Street entrance ramp and
the 45th Street exit ramp. All main lanes of the highway will still be
This change should primarily impact drivers during evening peak hour when
northbound MoPac is congested and some drivers use the auxiliary lane to
try and queue jump, or get ahead of other drivers. We expect the closure to
be implemented over the weekend and be fully in place by Sunday morning
