The new TxDOT bridge will replace the existing truss bridge over the Colorado River in Columbus, Texas.  Stiver Engineering provided construction consulting to the bridge contractor with cofferdam designs for crane access on both banks of the Colorado River.  The cofferdams allowed the crane to get closer to the center of the proposed bridge so that the bridge beams could be lifted and installed.  The cofferdam was constructed using driven sheet piles, wales and cross ties.

The SH 288 Reconstruction Project includes improvements that encompass a 10.3-mile stretch from US 59 to the Harris County line at Clear Creek and involves the expansion of three major interchanges:

  • Beltway 8, which will include (8) new direct connector/ramp bridges.
  • Loop 610, which will include (8) new direct connector/ramp bridges.
  • The Texas Medical Center, which will include (2) new direct connector/ramp bridges.

Stiver Engineering provided construction consulting through the demolition design and plans for the Southmore Boulevard Bridge, Holly Hall Street Bridge, 610 Interchange Bridges, SH 288 Bridges at Bellfort Street and SH 288 Bridges at Holmes Road.

The Yale Street Bridge has been around since 1931 and was listed on the National Register of Historic Places in Houston, Texas.  The bridge, among the lowest-scoring in the area in terms of modern standards, has been a source of discussion for years as commercial development to the south has increased.  TxDOT nearly closed the bridge in 2012, when trucks weighing more than 3,000 pounds per axle were restricted from using it because of structural concerns.  The bridge was reinforced with fiber reinforcing in 2013 and the load rating was increased to 10,000 pounds per axle.  This new rating still kept many trucks delivering goods to the stores and restaurants along Yale and Heights Blvd. from using the bridge.  After 85 years of serving the public, the bridge was demolished in 2015.  The new bridge will have two 14-foot wide outside lanes to accommodate turning for trucks, two 11-foot wide inside lanes and 5-foot wide sidewalks in each direction.  The bricks from the original bridge deck will be reused on the sidewalks.

Stiver Engineering provides construction consulting through structural analysis and works with contractors to develop demolition plans for bridges and elevated structures.

Due to a number of issues, there was a 1.1-mile gap in the Trail at Lady Bird Lake in Austin, Texas. Along this gap, visitors had to divert onto the narrow sidewalk and travel along busy Riverside Drive, crossing six lanes of I-35 access roads to travel east or west and use the south side of the trail.  There are currently 3,000 to 15,000 people using this trail every day of the year. The client retained Stiver Engineering provided structural design through design review services for the construction of each of the boardwalk precast sections.  

Stiver Engineering reviewed the design of more than 2,300 different shaped precast panels that were required to complete the trail. This process included the analysis of the reinforced concrete panels for lifting, transporting, and installation.

This project specified the expansion of the County Road 31 bridge over Oyster Creek in north Brazoria County, Texas. Our primary goal was to provide the project’s contractor with temporary construction bridge designs, which consisted of driven steel piles, w-sections, and hardwood timber.

Stiver Engineering provides structural design to contractors throughout the United States with construction bridges over rivers, bayous, ditches, and pipelines to ensure the safe transportation of workers and materials in and out of construction sites.
