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

Providing communities with roads, signalization, and proper drainage solutions, BBI designed the reconstruction of 4.1 miles of US 290 from west of Roberts Road to east of Bauer Road.  The existing divided rural section of asphalt with paved 2 lane roadways were reconstructed to provide an urban freeway configuration.  Grade separations were designed at Roberts Road, Becker Road and Bauer Road, utilizing a three span prestressed concrete beam superstructure. The project included three signalized intersections and three storm water detention basins.  The design expertise included grading, storm sewers, lime treated subgrade, cement stabilized base, asphaltic concrete pavement, concrete pavement, retaining walls, structures, storm water detention facilities, utility adjustments, signing and pavement markings, illumination and traffic signals.

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.

Austin's Great Streets Program:  Second Street Improvements

Creating a unique sense of community within downtown Austin, BBI provided preliminary engineering services, design phase, and construction services for Phase One of the Second Street "Great Streets" Project. BBI is currently providing all the above services for Phase Two - between Congress and Trinity - and will work on Phase Three - between Colorado and Congress Ave. 

In conjunction with the completion of a new Austin City Hall, BBI prepared plans, specifications, and bid documents for reconstruction of Second Street between San Antonio and Colorado.

This newly designed area includes:

• A 30' wide street with 32' wide sidewalks lined with trees and arbors, sidewalk cafes, outdoor marketing areas, and art pieces.  Together this design creates a unique sense of community within the downtown area of Austin.
• Design of over 23,000 square feet of concrete sidewalks along with special curb ADA ramps.
• Design of a special cantilever foundation to accommodate existing utilities for street lights, traffic signals, and trellises.  This design included 900 tons of asphalt, tree planting with irrigation and drains.
• Design of new storm sewer piping from 18" to 54" and 6" x 3" box culverts requiring a special outfall to protect the environmentally sensitive Lady Bird Lake. 
• Utility Coordination of more than 20 lines from private utility and communication partners.

Meeting the challenges, BBI's experts continue to work on Phase 2 providing the City of Austin with reliable design and construction services while supporting the communities.

Designing much needed roadways for communities within the City of Allen, BBI met the challenges with the design of the Exchange Parkway.  This project included a six-lane, 7,500 linear foot divided arterial with sidewalks in Allen, Texas from SH 5 to Angel Parkway. 

Project Challenges Include:

• The construction was limited to the outside four-lanes. 
• The adjacent property had been already developed as residential subdivisions. 
• The project was complicated by the subdivisions on one side of the road that were built five feet higher than the other side. 
• There was a shallow 84 inch water main located in the median of the project. 

Meeting the Challenge:

• The road section was manipulated to reduce the retaining walls to two-three feet without any impact to the drivability of the road. 
• The project included an alignment study and right-of-way acquisition. 
•  Extreme care was taken in designing the median landscaping, irrigation, and street lighting to prevent damage to the water main.  The water system and storm sewer system connected the existing systems into a complete system. 
• Extensive traffic control plans were prepared along with signalization of three intersections.
