Madison County Bridge No. 123 / 600 W over White River

Project Description: Madison County Bridge No. 123 carries CR 600 West over the White River in Madison County. The structure is a four-span, continuous variable depth concrete girder with simple span concrete end-spans. The rehabilitation project included a complete deck replacement and reconstruction of the end-spans with prestressed concrete I-beams making them continuous with the existing historic concrete girders.

United developed a design and construction method for this structure that allowed for the deck replacement without any temporary supports for the historic girders. The negative moment reinforcement in the deck was maintained over the girders and the new deck constructed above this reinforcement using a staged pour sequence to reduce construction loading. The design also eliminated two expansion joints by making the approach spans continuous with the main span. This eliminated on-going maintenance concerns for the County and significantly extended the useful service life of this structure. These unique design concepts saved the county in both construction cost and schedule.

Approximate Construction Cost: $1,200,000

Wabash County Bridge No. 645

Project Description: Rehabilitation of the existing historic timber covered bridge in North Manchester, Indiana. The construction involved temporarily supporting the bridge while members of the timber trusses were removed and replaced or repaired. The existing members had to be inspected to determine if they could be reused or if they needed to be replaced. Replaced members had to closely match the original look of the timber bridge for historic purposes. A new timber shake roof was placed, the siding repaired and repainted, and the bridge was re-leveled to its original appearance. At completion, the bridge reopened to both pedestrian and vehicular traffic.

Steve Olsen of North Manchester Real Time Photography documented the bridge’s rehabilitation in the following video.

146th Street from SR 37 to Boden Road

Project Description: 146th Street Extension Project from SR 37 to Boden Road; four-lane urban section designed to allow for future six-lane urban expansion, including landscaped median, multi-use paths, and curb & gutter; three miles of new roadway on new alignment combined with pavement reconstruction and widening, including two bridges.

This roadway extension and added travel lanes project necessitated the completion of an Environmental Assessment. Major environmental services investigated during the completion of this documentation included a noise analysis, wetland determination and delineation. It also included coordinating with the Local MPO to ensure compatibility with the Regional Transportation Plan and air conformity analysis. The project resulted in extensive coordination with the Indiana Department of Environmental Management and the US Army Corps of Engineers due to project impacts upon wetlands. The project resulted in a Section 401 Water Quality Certification from the Indiana Department of Environmental Management and an Individual Permit from the US Army Corps of Engineers.

Carroll County Bridge No. 142

Project Description: The project consisted of the construction of an eight-span, variable depth, reinforced concrete Girder Bridge carrying Carroll CR 250 W over the Wabash River. Project also included a new widened deck slab, end bearing replacement, new expansion joints, replacement of one girder section, and approach improvements. Project necessitated coordinating with the Indiana Department of Natural Resources, Division of Historic Preservation and Archaeology (SHPO), and other Section 106 Consulting Parties to work towards an amicable solution. This coordination was documented in a Memorandum of Agreement (MOA) that became a part of the environmental documentation for the project. In addition to historic concerns, the project also required further coordination and investigation with the U.S. Fish and Wildlife Service to ascertain possible impacts to a Federally endangered mussel. This coordination resulted in special construction techniques to limit any possible impacts to this species.

I-70 over Wabash River – Vigo County

Project Description: The rehabilitation of the I-70 bridge over the Wabash River in Vigo County required extensive research in order to develop a rehabilitation project that would meet the needs of the State while maintaining traffic during construction. The bridge is 1,961 feet long with 21 spans consisting of steel rolled beams and steel plate girders with a reinforced concrete deck. Preliminary design included multiple options for widening the existing bridge which compared construction cost, user cost, and impacts to sensitive environmental areas around the Wabash River. United successfully developed a project that met all of this criteria while also meeting the user demand for continuous use during construction.

Approximate Project Cost: $12,000,000

96th & Fall Creek Roundabout

Project Description: The project consisted of the reconstruction of a two-way urban road with a two-way turn lane and two major intersection improvements with one signalization and one roundabout. The intersection was initially scoped as a signalization, but determined that a roundabout would operate at a higher level of service (LOS) and have safer operations. The maintenance of traffic for this project included a significant closure on 96th Street which is a heavy commuter route. The success of the MOT was a result of good communication with the bordering properties, exceptional advanced route detour signing, and disseminated public information.

Approximate Project Cost: $2,800,000

Wabash County Bridge No. 505

Project Description: Rehabilitation of a 100-Year Old Historic earth-filled concrete spandrel arch bridge carrying Ferry Street over Vermont Street and Charles Creek.

This bridge rehabilitation project needed the completion of a Categorical Exclusion, Level 3 / Programmatic Section 4 (f). This type of environmental documentation was required due to the project’s impact on a bridge identified as a candidate for the National Register of Historic Places. As a result, the project required exhaustive coordination with Section 106 Consulting Agencies in an effort to satisfy historic concerns. Stipulations remediating the project’s effect on the bridge were documented in a Memorandum of Agreement. Additionally, the bridge was also photographically documented in accordance with current standards as stipulated in the project’s Memorandum of Agreement.

Approximate Project Cost: $750,000

I-70 Interchange Modifications at US27

Project Description: 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 bearing s 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.

Approximate Project Cost: $2,700,000

I-65 Added Travel Lanes in Boone County

Project Description: Design/Build project for the reconstruction and widening of 12.8 miles of I-65 between I-865 and US 52 included: seven partial interchange reconstructions; pavement widening; added travel lanes; pavement reconstruction; retaining walls; local road improvements; four bridge replacements; seven bridge rehabilitations; CSX Railroad bridge replacement, CSX Railroad track re-alignment; signing; wetland mitigation; and transportation management plan.

This two-phase project involves adding travel lanes to I-65 from the I-865 interchange to US 52 just north of Lebanon. Phase 1 is a Design/Build project that involves adding one travel lane in each direction from I-865 to CR 100 and milling and resurfacing the existing lanes. Phase 2 is a Design/Build project that involves adding one travel lane in each direction and a full reconstruction of the existing pavement.

United Consulting served as managers of the field survey for this project. This included coordination with an aerial survey consultant and two additional ground survey consultants and performing a great deal of the ground supplemental survey, as well as providing ground and aerial control for the entire corridor. When additional pavement elevations were required during design, United Consulting coordinated with the INDOT district and traffic control consultant to collect this vital information overnight on this highly-traveled interstate.

The environmental services required by this project included the completion of a Level 3 Categorical Exclusion. Major environmental services investigated during the completion of this documentation included cultural resources investigations, noise analysis, phase I and phase II investigations, and a wetland determination and delineation. The project also resulted in coordination with the Indiana Department of Environmental Management and the US Army Corps of Engineers due to project impacts upon jurisdictional waters. The project resulted in a Section 401 Water Quality Certification from the Indiana Department of Environmental Management, a Regional General Permit from the US Army Corps of Engineers and three Construction in a Floodway Permits from the Indiana Department of Natural Resources. The project also required the completion of a Cemetery Development Plan due to construction disturbance within 100.0 feet of a nearby cemetery.
