Bridge and Interchange Design

  • Diamond Interchange, Irving - Structural Engineering Principal for a portion of a 5-level interchange of four major urban highways: SH-183, SH-114, Loop 12, and Spur 482. The structural scope of work includes 12 concrete bridges with a total deck area of about 820,000 sf.
  • SH-121/IH-35E Interchange, Lewisville - Structural Engineering Principal for a 5-level suburban highway interchange with 4 miles of elevated concrete and steel structure, including 12 bridges with 25 miles of straight and curved bridge beams, and columns more than 100 ft high.
  • Vitruvian Park Bridges, Addison - Structural Engineering Principal for three "signature" steel arch bridges in a new urban town center development. The Ponte Avenue Bridge is a single-span, 127 ft, prestressed concrete U-beam structure with cantilevered abutments and steel arches. The Bella Lane Bridge is a 3-span, 141 ft, prestressed concrete box-beam structure with steel arches. The Southern Pedestrian Bridge is a single-span, 150 ft, arched steel truss structure. This fast-track project was designed in only eight weeks and constructed in less than a year.
  • SH 161 Design/Build Project, Grand Prairie - Structural Engineering Principal for Bridges 20, 21 & 29 and Direct Connector Ramps 37 & 38. Bridge 29 has staged construction with flared deck edges. The abutments are soldier pier walls. Ramp 37 is a Direct Connector that includes two 2-span steel units.
  • Dallas North Tollway Bridges and Overpasses, Denton County - Structural Engineering Principal for two bridges and three overpasses for an 8-lane divided tollway. The project includes complicated geometry, super elevation, transitions, significant bridge scour effects, agency coordination for aesthetic design, and abutment designs for an ultimate 10-lane configuration.
  • Westpark Tollway, Fort Bend County - Structural Engineering Principal for four highway bridges, including two on main lanes and two on frontage roads, with prestressed slab beams, Type B beams, flared decks, and prestressed concrete railings.
  • Margaret Hunt Hill Bridge, Dallas - Structural Engineering Principal for preliminary planning and design of a twin-structure, 800 ft clear-span steel arch bridge carrying eight lanes of Woodall Rodgers Freeway traffic over the Trinity River.
  • Santa Fe Trestle Trail, Dallas - Structural Engineering Principal for a hike and bike trail across the Trinity River floodplain. The project includes more than 1,140 ft of curvilinear bridge structures, including 13 spans of cast-in-place concrete, 2 spans of steel, and the renovation and reuse of an historic railroad trestle.
  • East 40th Street/International Parkway Overpass, DFW International Airport - Structural Engineering Principal for a 55 ft wide by 302 ft long, 3-span bridge using precast concrete U-beams on rectangular columns with full-height abutments.
  • International Parkway Bus Ramps, DFW International Airport - Structural Engineering Principal for a 31 ft wide by 460 ft long entrance ramp bridge and a 31 ft wide by 235 ft long exit ramp bridge. Both bridges have a tight 150 ft radius, with curved 3-span continuous, cast-in-place post-tensioned concrete box sections. The entrance ramp also includes a precast concrete U-beam tangent section.
  • C-RAC Bridges, DFW International Airport - Structural Engineering Principal for seven bridges ranging in size from 1-span, 50 ft long bridges to 4-span, 280 ft long bridges. All 7 bridges have a special rail, Type A, B, and C beams, inverted tee bent caps, flared deck sections, and full-height abutments.
  • US-83 Overpasses, Hidalgo County - Structural Engineering Principal for six bridge replacements along US-83 adjacent to the US-281 Interchange. Type IV beams were utilized on five overpasses and prestressed concrete box beams were used on one overpass. The bridges have inverted tee bent caps, rectangular columns, footings, drilled shafts, and soldier pier abutment retaining walls. This project was produced entirely in metric units.
  • US-77/US-83 Braided Ramps, Cameron County - Structural Engineering Principal for two 28 ft wide by 550 and 476 ft long braided ramps. Both ramps have compound reverse curves, two straddle bents, inverted tees and utility piping.
  • UT Southwestern Medical Center Bridge, Dallas - Structural Engineering Principal for a 62 ft wide by 255 ft long, 4-span continuous curved bridge. This bridge is a cast-in-place, post-tensioned concrete box-girder structure with a horizontal radius of about 272 ft.
  • FM-2499, Section 3 Bridge and Culvert Widening, Denton County - Structural Engineering Principal for the 4-lane widening of a 375 ft long, 5-span bridge and an adjacent, 8-cell box culvert, both with substantial skew.
  • Oak Cliff Fellowship Pedestrian Tunnel, Dallas - Structural Engineering Principal for a 200 ft pedestrian and utility tunnel under Camp Wisdom Road, connecting an existing church complex to a new education building.
