Industries: Highways and Bridges

The Marsha Sharp Freeway is Lubbock’s primary east-west access road. It provides a western connection to West Loop 289, gives greater access Texas Tech University, downtown Lubbock and other high traffic areas and encourages development of the central business district.
Terra provided a complete geotechnical soil investigation and foundation recommendation for structures associated with the Marsha Sharp Freeway. Terra drilled over 200 borings with depths ranging from 20 feet to 150 feet.

The project has been in development since the 1980s and was completed in five phases and consisted of the following structures:

  • Widening of West Loop 289 from four to six lanes from 34th Street to Slide Road.
  • Rebuilding frontage road system under the main lanes—three lanes on each side.
  • Building the 50th Street overpass and extending 50th Street to Frankford.
  • Building the complete freeway from Salem Avenue to Avenue L.
  • Building 19th St., Quaker Avenue, Fourth Street and Avenue Q interchanges.
  • US 82 main lanes and fly overs at Loop 289.
  • US 82 from Chicago Avenue to Salem Avenue.
  • Building the I-27 interchange.
