-
The 183 North Mobility Project will improve cross street bicycle and pedestrian connections, as well as add sidewalks compliant with the Americans with Disabilities Act (ADA) along the US 183 frontage roads in locations where sidewalks do not currently exist.
-
Tolls will be waived for Capital Metro buses on the completed 183 North Mobility Project Express Lanes. New and repaired sidewalks compliant with the Americans with Disabilities Act (ADA) will also improve bus stop accessibility.
-
The 183 North Mobility Project will include improvements to cross street connections for bicyclists consisting of bike lanes in each direction, created by re-striping the existing cross street pavement.
-
The 183 North Mobility Project will provide safe connectivity for bicyclists throughout the corridor, closing existing gaps to provide a network of continuous bike lanes available to cyclists traveling between SH 45 North and MoPac.
-
The 183 North Mobility Project will improve and add sidewalks and business driveways where Americans with Disabilities Act (ADA) compliant facilities do not currently exist.
-
In addition to adding express lanes, the 183 North Mobility Project will improve the non-tolled portions of US 183 by adding a fourth general-purpose lane in areas where only three currently exist.
-
The 183 North Mobility Project is being constructed by the Central Texas Regional Mobility Authority to improve safety, optimize system connectivity and enhance local mobility along the US 183 corridor.
-
The 183 North Mobility Project extends 9 miles from SH 45 North to MoPac in northwest Austin and will reduce travel times and improve mobility for commuters, local drivers, visitors to the region, and people who prefer to use public transit, ride their bike or walk.
-
The 183 North Mobility Project limits the proposed roadway improvements to within the existing right-of-way. Express lanes will be constructed where the current median exists now.
-
Traffic congestion along US 183 between SH 45 North and MoPac is a major issue, especially during peak rush hour periods. The 183 North project aims to provide less congestion and more reliable travel with the addition of two tolled express lanes in each direction and non-tolled general purpose lane improvements.
-
Tolls will be waived for Capital Metro buses on the completed 183 North Mobility Project Express Lanes. The project's aim to reduce congestion will also mean more reliable travel times for public transit.
-
As part of the 183 North Mobility Project, operational improvements will be made to MoPac that include express lane direct connectors from the southbound US 183 managed lanes to a new southbound non-tolled collector-distributor roadway providing direct/bypass access to W. Anderson Lane/Spicewood Springs Road and Far West Boulevard.
-
The 183 North corridor provides access to downtown Austin, as well as businesses, major employment centers, religious institutions, schools, parks and trails, recreational centers, and residential areas, all of which would benefit from a reduction in congestion and reliable travel times for drivers, transit and emergency responders.
-
Traffic congestion along the nine-mile stretch of US 183 between SH 45 North and MoPac is a major issue. Four improved non-tolled general-purpose lanes in each direction and two tolled express lanes in each direction will reduce travel times and improve mobility for commuters, local drivers, and visitors to the region.
-
To improve safety, optimize system connectivity and enhance local mobility along the US 183 corridor, the 183 North Mobility Project will construct two tolled express lanes and add a fourth general-purpose lane in areas where there are only three.
