FEATURED PROJECT

I-70 and US 27 in Richmond, Indiana

Client:  Indiana Department of Transportation

The US 27 over I-70 bridge is a two span continuous composite steel plate girder structure with a total length of 182 feet. It consists of a complex geometry and design with access ramps tying in at each corner of this single point interchange.

This interchange was designed to increase traffic flow by reducing the number of traffic signals to efficiently move traffic to and from the ramps and along US 27 mainline. Large “edge girder” members were designed with connections to multiple members which carry the forces and moments to the large splice plates which rest on pot bearings located on either side of the center pier. 

More than 430 tons of structural steel and over 2000 cubic yards of concrete were used for this structure. Curved, open window, decorative bridge railing sits atop the bridge deck, and tinted ashlar block architectural treatment accent the pier face and retaining walls below.

 

 

 

 

Bridges

United Consulting has provided structural engineering services for a wide range of projects from large interchange projects to small county bridge projects. We approach every structural project with the goal of providing the client with appropriate, on-schedule, cost effective solutions.

Our bridge projects include not only innovative bridge solutions but many times require complex hydraulic modeling, retaining wall layout and design. And of course, every project is accompanied by a reliable, detailed cost analysis.  

United Consulting has partnered with 32 Indiana counties in participating in the FHWA National Bridge Inventory Program. Our goal is to not only satisfy the requirements of the program, but also to provide our partners with a detailed snapshot of their bridge assets that can be used to allocate future resources.  

United Consulting bridge services include:

  • Steel plate girder and rolled beam structure design
  • Prestressed and post-tensioned, segmental concrete structure design
  • Conventional cast-in-place and post-tensioned concrete slabs
  • Bridge rehabilitation including historical restorations, covered timber trusses, superstructure replacements and seismic retrofits
  • Bridge Inventory services and emergency structural condition evaluations
  • Conventional cast-in-place, concrete drilled shafts, soldier pile, sheet pile and mechanical stabilized earth retaining walls
  • Bridge, small structure, and floodplain hydraulic analysis
  • Post bid services for contractors including temporary bridges and wingwall design
  • Water Resources: including complex hydraulic analyses, hydrology, flood plain mapping and bridge scour analysis.
