Project Description:  This multi-agency project with INDOT, City of Fishers, and Hamilton County provided a new interchange on I-69 at 106th street that has served as a catalyst for economic development while reducing congestion along the busy I-69 corridor. The purpose of the project was to create a new access point to I-69 and improve the traffic operations of the adjacent interchanges at 96th Street and 116th Street. United was selected and worked through the evaluation of the different interchange alternatives. The chosen alternative for the interchange featured a two-lane, oval-shaped roundabout on 106th Street over I-69 including ramps to and from both directions of the interstate. Two separate two-lane bridges carry one direction of traffic. The westbound traffic bridge on the north side of 106th Street was also designed to accommodate pedestrians.

Approximate Construction Cost:  $21,000,000

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.

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

Project Description:  US 231 Phase III Project in Spencer County is comprised of new terrain freeway totaling 4.5 miles of four-lane divided roadway with a grass median and two bridges in Spencer County.  The project includes a railroad grade separation and a diamond interchange at SR 162.  The project traverses densely wooded new terrain with large elevation changes and strip pits from past mining activities.  Four local roads were relocated to maintain the limited access feature of the new US 231 freeway.

The project required extensive coordination with the INDOT Office of Geotechnical Engineering due to possible mine subsidence, ponds, and the types of soil identified in the soil boring including coal, shale, and sandstone.  The project bisects three local service roads, a railroad, and State Road 162.  Coordination with the local agencies, Hoosier Railroad identified solutions to minimize the new alignments impacts on the community.

The location control route survey and topographic survey included full ground survey on a terrain that included over 100 feet of elevation changes, ponds, and strip mines. The new alignment traversed land with elevation changes of more than 50 feet and was previously mined.  Mining operations created unique geotechnical challenges which were coordinated as the project encountered mine spoils and created ponds.

Approximate Project Cost:  $25,500,000

Breadth of Services Provided:  Topographic Survey, Regulatory Permit Applications,  Roadway Design, Bridge Design, Complex Sign Design, and Utility Coordination

Project Description:  With the goal of reducing congestion and improving safety and mobility along the route, United completed preliminary and final design on 15 bridges for the upgrade and realignment of US 31 from US 30 in Plymouth to the US 20 bypass in South Bend.  These projects included multiple bridge types from single-span prestressed girders to a three-span steel plate girder structure with integral post-tensioned straddle bent pier caps at a single-point interchange.

United also completed the “Fast Track” rural five-mile Grading Contract and the more complex urban design in the northern two miles.  The six different urban Contracts included pavement reconstruction, retaining walls, local road improvements, bridge replacements, signing, signal design, and a single-point urban interchange.

This project is part of the larger Major Moves initiative to upgrade the route to freeway standards from Indianapolis to South Bend.
