TxDOT Waco IH 35 Project

Binkley & Barfield, Inc. is providing final design engineering services and PS&E on the IH 35 widening between LP340(S) and LP340(N).  This project involves the widening of 8 miles of IH 35 to 8 mainlanes and two, two-lane frontage roads and bridges.  Side road ditch drainage was replaced with storm sewers, and 25 bridge replacement designs are included. The project includes the signature main lane and frontage road bridge crossings of the Lake Brazos. The project required a very complex Traffic Control Plan and Construction Sequencing due to the ADT of 133,000 with high volumes of heavy truck traffic.  Temporary transitions and lane detours had to be reinforced with new base and surfacing prior to traffic change during construction.

Project Scope includes:

• Route & Design Studies
• Right of Way Data
• Roadway Design Controls
• Three Level Interchange
• Drainage Studies
• Direct  Connectors
• Signing, Markings, and
• Signalization
• Bridge Design
• Retaining Wall Layouts & Details
• High Mast Illumination
• Utility Design & Coordination

  BBI provides complete coordination of the IH 35 TxDOT project, bringing all the partners together.  Partners include:

Providing collaboration between TxDOT and the Harris County Toll Road Authority, BBI met the design challenges of the extension of the US 90A/Fort Bend Parkway interchange (northern terminus of the Fort Bend Parkway toll road into Harris County).  The scope of services provided by BBI included design studies, completion of roadway design schematics, field surveys, roadway design, drainage design, and two direct connector bridges.  Both bridges were combination of Type IV prestressed concrete beam/ steel girder structures.  The eastbound connector to US 90A was a 3rd level connector 1859 linear feet (LF) long and the westbound connector to US 90A was a 4th level connector 2137 LF long.

Stormwater runoff was mitigated through the design of multi-cell detention basins within the interchange.

Design challenges included provision for a future depressed section under US 90A by a continuation of the parkway northward and accommodating ongoing final design by TxDOT of the US 90A reconstruction.  Through careful evaluation of the problems and strategic planning, BBI successfully completed the project maintaining consistent traffic control, zero drainage hydraulic impact to the vicinity, and coordination with area transportation organizations.

Engineering Services Provided Include: 

• Design Studies
• Roadway Design Schematics
• Field Surveys
• Roadway Design
• Drainage Design
• Two Direct Connector Bridges

The project was a joint effort between the two owners, TxDOT and the Harris County Tollroad Authority, requiring complex criteria addressed in an effective cost-conscious manner.  BBI strengthens communities through collaboration and by completing projects on-time and within budget.

BBI provided strategic planning and careful evaluation of the problems of the Westpark Tollway expansion.

With over 370,000 vehicles daily flowing through the US 59 and IH 610 Interchange in Houston, BBI successfully completed the project while maintaining consistent traffic control, zero drainage hydraulic impact to the vicinity and coordination with area transporation organizations.

The scope of services provided by Binkley & Barfield, Inc included:

• route and design studies
• field survey
• roadway design controls
• drainage design
• and bridge design. 

The project included thirteen direct connectors, US 59 mainlane, and HOV bridges to take bi-directional toll road traffic and frontage road traffic under the existing US 59/IH 610 interchange.  Storm water runoff was mitigated through the design of two detention basins located within the interchange.  Two pump stations were designed to discharge the storm water to an existing outfall structure adjacent to the project.  The use of drilled shaft retaining walls allows for future bridge foundations to be located behind the walls and were also used for bridge abutment foundations. 

The Westpark Tollway and US 59/IH 610 Interchange project involved complex criteria to be addressed in an effective, cost conscious manner.  The fast track construction included thirteen mainlanes, HOV and direct connector bridges,complex traffic control for the US 59/IH 610 Interchange, zero drainage hydraulic impact to the vicinity of the interchange, detention basins, complex design and construction coordination.
