SH 249 (Tomball Tollway), Phases I and II

SH 249 (Tomball Tollway), Phases I and II Tomball and Montgomery County, Texas DCCM was contracted by the Harris County Toll Road Authority (HCTRA) as the Program Management Consultant (PMC) for the design and management of both preliminary and final project designs, as well as construction management and inspection services for Phase II. We developed a project feasibility assessment, which resulted in the SH 249 (Tomball Tollway), Phases I and II engineering feasibility report, and served as the basis for the final design. On its first day of operation, eager toll users doubled the projected 17,000 daily toll transactions, cutting traffic on the existing frontage road in half. Funded entirely with toll road revenue paid by drivers who choose to use the Harris County toll road system, the final construction will extend the toll road into Montgomery and Grimes Counties to SH 105, streamlining trips to and from rapidly growing Grimes County and College Station. Phase I: Spring Cypress Road to FM 2920 This project provided travelers with four main lanes in each direction and was constructed between the existing TxDOT northbound and southbound non-tolled frontage roads. As PMC for HCTRA, DCCM completed an aggressive 9-month design program to deliver plans, specifications, and estimates (PS&E) for HCTRA to bid and construct this phase. DCCM provided leadership, schedule adherence, quality assurance, and oversight to 17 consultants, completing the PS&E for four new toll lanes in each direction along a 6-mile stretch of SH 249, adding five new bridges, retaining walls, and a drainage system that mitigates flooding. Drivers may now bypass seven stoplights while the frontage roads remain toll-free. All milestone submittals were met on time, and the project was constructed in only 16 months and under three construction contracts. Phase I was open to traffic in April 2015 and is exceeding all revenue forecasts. Phase II: FM 2920 to Spring Creek (Harris/Montgomery County line) Design preparations for Phase II began in October 2014 with design revisions to the TxDOT 2006 SH 249 Schematic. As in Phase I, DCCM was the PMC for the design of four-lane toll lanes in each direction, adding three-lane frontage roads on both north- and southbound approaches, five major bridges, flood-mitigating storm sewer detention, a collegiate practice field, and equestrian and bike trails. Services also included computing cut-and-fill quantities for roadway sections, concrete and reinforcement steel quantities for bridge deck pours, and payments for such pours on the contractor’s pay estimate. DCCM monitored the roadway excavation, subgrade preparation, concrete milling, embankment placement for abutments, installation of drill shaft and foundations, concrete beam placement, asphalt pavement placement, bent footings, column, cap pours, reinforced earth walls, 18- to 36-inch reinforced concrete pipes, and various concrete box culverts. Our team oversaw construction management and inspection services for this segment of the project. Phases I and II of the SH 249 (Tomball Tollway) project included environmental investigations and permitting, survey/ROW mapping, utility identification and assessment, subsurface utility engineering, and hydrologic and hydraulic modeling and detention pond design. DCCM also provided construction phase services for Phase II and the direct connectors at SH 99 (Grand Parkway). Mainlanes, Phase I, Section 1 – Montgomery County MCTRA selected DCCM to prepare PS&E for mainlane and ramp construction for a 0.4-mile section of tollway north of Tomball, Texas. The project scope included roadway geometric design, traffic control plans, removal plans, drainage plans with both open and closed systems, SWPPP, cross-sections, general notes, specifications, and construction cost estimates. The DCCM team coordinated with both adjacent designers on the Montgomery County segment and with the design and construction teams of the Harris County segment to the south to deliver a synchronized product that minimized impacts to travelers and adjacent property owners and reduced overall project costs.

West Terre Haute Trail

West Terre Haute Trail West Terre Haute, IN This one-mile-long pedestrian trail is located along the south side of US 150 in West Terre Haute, beginning at Sumner Avenue and extending east to Schley Place. The goal of this project was to improve pedestrian safety, increase connectivity, reduce congestion, and improve air quality. Prior to construction, pedestrians were forced to walk along the narrow US 150 shoulder beside traffic or behind the guardrail adjacent to the steep side slope, creating a dangerous and restricted walking path. With this project, West Terre Haute was able to provide an alternate route for commuting individuals, families, and those needing to access jobs without vehicles. This trail and bridge improved safety for pedestrians and vehicular travelers amidst increased US 150 traffic.

Telephone Road, Lawndale Street, South 75th Street, and Almeda Road Bridge Replacements – DCCM provided preliminary and final design and bid and construction phase services for the replacement of the four bridges. DCCM investigated the site, reviewed record drawings and existing utilities, and conducted a topographic survey of the existing channel and bridges to supplement the data. DCCM assisted with the coordination of lane configurations and sidewalk widths to determine typical bridge sections and prepared exhibits showing alternatives for each bridge. DCCM prepared TCPs, local drainage design, SWPPP, a drainage area map, hydraulic calculations, and drainage standards. Stella Link Road and Ardmore Street Bridge Replacements – DCCM provided the design, coordination, scheduling, and PS&E for the replacement of the existing Ardmore Street bridge and addition of a new span to the Stella Link Road bridge. The project increased the hydraulic capacity of Brays Bayou by expanding the cross-sectional area under the bridges. The new bridge at Ardmore Street provided a U-turn, wider lanes, and sidewalks for community connectivity. The project included a compressed schedule to meet federal funding requirements, environmental issues, and utility coordination due to gas lines, storm sewer, gravity and force main sanitary sewers, and electrical and water lines on the bridges.
