Project Description

Arias is currently providing Geotechnical Engineering services for design and eventual construction of the US 183 North Mobiilty Project for the Central Texas Regional Mobility Authority (CTRMA) in Austin, Texas. The project extends from State Highway (SH) 45 North/Ranch-to-Market (RM) 620 to State Loop 1 (MoPac), a distance of approximately nine (9) miles and consists of the construction of four express lanes (two in each direction) and widening of the existing United States Highway (US) 183 as required to bring the total number of general purpose lanes to four in each direction. Other improvements include the addition of direct connector ramps providing access between the existing express lanes on MoPac and the new express lanes on US 183.

Bicycle and pedestrian improvements include an 8-foot wide Shared Use Path to connect the existing Jollyville Road bike lanes to the existing bike lanes on Pond Springs Road. An 8-foot wide Shared Use Path from existing bike lanes on Pond Springs Road to the existing bike lanes on Lake Creek Parkway adjacent to the US 183 northbound frontage road. Sidewalks along the US 183 northbound and southbound frontage roads from RM 620/SH 45N to Loop 360 in locations where sidewalks do not currently exist. Cross street connections for bicyclists consisting of 5-foot bike lanes in each direction, created by re-striping the existing cross street pavement to narrow the traffic lanes.

Geotechnical Engineering services included field investigations, engineering analysis, and pavement design support.
