Huitt-Zollars provided PS&E for Yager Lane/IH 35 in Austin, Travis County. The project involved replacing the existing Yager Lane Bridge over IH 35, adding two turnaround bridges, and redesigning the interchange at Yager Lane to a conventional diamond with elevated frontage roads. Huitt-Zollars determined the horizontal and vertical alignments and geometries, retaining wall alignments, intersection layouts and grading plans, master grading plans, design cross-sections, both roadway details and cost estimates.

Huitt-Zollars prepared plans for this urban express toll road in Harris County. The scope of services included surveying, roadway design, bridge layout and design, traffic engineering, traffic control planning, pavement markings, signage, signalization, cost estimating, drainage, utility coordination, and storm water pollution prevention planning.

This project involved the extension of Spur 366 (Woodall Rodgers) from east of IH-35E to west of the Trinity River with a tie into Singleton Boulevard, and a signature bridge at the main channel. West of the Trinity River, the project involves reconstruction of the existing Beckley Avenue/Continental Avenue cloverleaf interchange. Beckley Avenue is raised to the Woodall Rodgers level and converted to a signalized intersection with a western tie into the recent Singleton Boulevard rehabilitation project.

Huitt-Zollars designed a PS&E package for the construction of a new location six-lane freeway approximately two miles in length. Design plans included storm drainage, paving plan and profiles, culverts, bridges, four exit ramps, ramp toll plazas, and a detention pond grading plan. This project included seven bridges; two stream crossings; two structures adjacent and over the river east levee embankment; two ramp structures; and one elevated parkway structure. The bridges are located in a horizontal curve and include superelevation transitions.

Huitt-Zollars designed a PS&E package for two miles of six-lane, major depressed freeway construction. Design included two entrance and exit ramps with toll booths, up to eight lanes of continuous frontage roads, relocation of utilities, bridges and walls. The project involved both urban and rural storm drainage systems; four miles of retaining walls including cast-in-place, cantilever, and tied back wall systems; plus major prestressed concrete bridge overpasses at Josey Lane, Scott Mill, and Kelly Boulevard.

Huitt-Zollars provided final design and engineering drawings for three separate direct connectors in the SH-183/SH-161 interchange under the TxDOT Bridge Division Evergreen Contract. The work included completion of bridge layouts, bridge design, quantities, applicable standards, estimate, and the necessary special provisions and specifications. The work was designed in accordance with AASHTO Standard Specifications. The drawings were incorporated into a PS&E design package prepared by the TxDOT Dallas District.

Huitt-Zollars provided program and construction management services for the project, the first Design/Build transportation project for TxDOT. The project involved developing 49 miles of new location toll road between Georgetown and Seguin, Texas. Program management responsibilities included finalizing preliminary design, assisting with contractor qualifications evaluation, and developing project controls for the program.

Programming and architectural design services were provided for a 70,000-SF high-tech workforce training facility created for the energy industry. The project includes 28 classroom/laboratory spaces equipped with compressed air, 120V and 208V power and audio/video systems for engineering technology, automated manufacturing and corporate college programs, two simulation labs for drilling and crane operation, a high bay manufacturing area with a 20-ton rail crane, machine shops, quality control lab, and an administrative/faculty suite. Associate Architects: AUTOARCH Architects and Archi*Techn

Jesse H. Jones Hall is one of three buildings occupied by the UT School of Law with each building featuring a different architectural style and character. Morris, a Huitt-Zollars company, was commissioned to design office space to accommodate additional faculty and program directors. The commission also includes the restack/consolidation of the library from six floors to three floors. The UT Law Library is the largest in the U.S.

Huitt-Zollars designed a two-mile segment of IH-410 to widen the main lanes from six to ten lanes with retaining walls along the frontage roads, new overpass bridges at Callaghan and Babcock, and the redesign of seven entrance and exit ramps. The design included: roadway plans and profiles, bridge layouts, retaining wall layouts, signing, pavement marking, continuous illumination, and an extensive storm drainage system for the main lanes and frontage roads. The shop drawing review and construction phase support services were also included.
