MOT-Traffic Control Plans

Experience

SH 71 Express Toll Lanes Design/Build Project , Austin, TX:

Mr. Zamora was the Design Manager for the SH 71 Toll Lane TxDOT project from Presidential Boulevard to east of SH 130. The work included the construction of toll lanes with grade-separated crossings at FM 973 and SH 130, general purpose lanes, at-grade ramps, and intersection improvements. The project also included the realignment of FM 973 from just south of the Colorado River to a point 0.5 mile south of the current SH 71/FM 973 intersections. Mr. Zamora led the design team in the design of roadway, drainage, structural, SW3P, Traffic Control Plans (TCP), signing and striping, illumination, signal warrant analysis, landscaping, and civil works for toll and ITS hardware. As Design Manager, he performed constructability reviews of all TCP plans to ensure that the technical provisions were adhered to, and maintained access at all times to Austin-Bergstrom Int’l Airport and the direct connectors to SH 130. The TCP was designed using traffic studies and modeling of existing and interim conditions to demonstrate required LOS during construction.

IH 35 Segment 3a – TxDOT, Waco, TX:

Mr. Zamora was the Roadway Task Lead Engineer for the design of the PS&E on 6.4 miles of IH 35 in Bell County from just north of LP 363 in Temple to just north of the City of Troy. This segment of freeway was reconstructed from a 4- to 6-lane section with the conversion of frontage roads from two-way to one-way. Design included two intersection stack flips from main lane underpasses to overpasses. The TCP were a major component of the plans. Mr. Zamora designed the TCP to allow the contractor to have ample work zone while also allowing for the simultaneous acquisition of ROW. The TCP provided for continuous traffic flow on main lanes and frontage roads, and allowed for the relocation or adjustments of the utilities including water, sewer, telephone, and fiber optic joint bid work. This complex TCP was developed utilizing phases, steps and stages, allowing for expedition in critical locations. Coordination with adjacent projects on both ends of the project was vital in establishing safe and continuous traffic flow. As the project has progressed, Mr. Zamora modified the TCP to accommodate changing conditions and/or work progress.

Sam Houston Tollway East – HCTRA, Houston TX:

Scope of work was for the widening of the Sam Houston Tollway East (SHTE) in Pasadena. Limits were the northern half of Segment 2, stretching from north of Vista Road to north of Crenshaw Road. Mr. Zamora was responsible for complete TCP geometric roadway design to expand an existing 4-lane expressway to 8 lanes, along with modifications as needed to frontage roads, permanent and temporary ramps, and associated toll collection points – plan and profile sheets, design cross-sections, and TCP. He coordinated with multiple discipline-specific consultants on drainage, signage/pavement marking, illumination, landscaping, and communications.
