I-69 and 106th Street Interchange

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.

US 231 Phase III – New Road Construction

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

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.

Operation Indy Commute – I-65 & I-465

Project Description: This project included a new westbound I-465 to southbound I-65 fly-over ramp, added travel lanes on I-65 and I-465, ramp and median reconstruction, lighting, signing, retaining walls, and noise walls. The new bridge carrying westbound I-465 to southbound I-65 included 11 spans of pre-stressed concrete I-beams and is approximately 1,400-feet long. The entire design was completed on a fast track, 15-month schedule with United Consulting teaming with American Structurepoint to deliver this successful project for INDOT.

Approximate Project Cost: $40,000,000

Jackson Street Causeway Pedestrian Walkway

This year, the Town of Cicero’s Lights Over Morse Reservoir Festival during the July 4^th weekend not only celebrated our country’s independence but also celebrated the opening of the long-anticipated walkway. The new walkway provides a safe way for residents move from one side of the town to the other side over Morse Reservoir. This beautiful new community fixture was much-needed and provides more accessibility and connectivity to the town.

Project Description: This project provides a walkway along the Morse Reservoir Jackson Street causeway and provides a safe pedestrian connection between Red Bridge Park and Community Park on each side of the reservoir.

The three main spans over the waterway utilize prefabricated steel trusses while the 18 remaining spans utilize side-by-side prestressed concrete double-t beams with a concrete overlay. Shell-piles proved to be a cost effective solution for the 21-span structure. Steel sheet piling with a concrete facing tie the proposed walkway into the existing topography. Decorative pedestrian railing and lighting provides safe passage for pedestrians while also enhancing the aesthetic impacts to the trail.

A major challenge for this project was coordinating the construction with the existing utilities, which included overhead power lines parallel to the alignment of the pedestrian bridge. The power utility temporarily de-energized their power lines so the contractor could set the bridge components, and permanently relocated their facilities onto the new pedestrian bridge.

Approximate Construction Cost: $2,400,000

Interchange Modifications at I-465 and I-74

Project Description: The project included the complete reconstruction of the system to system interchange at I-465 and I-74. It also reconstructed the interchange access from I-465 to Brookville Road and Shadeland Avenue. The interchange configuration involved extensive coordination with geotechnical to determine the most cost-effective solutions for the fly-over ramps. It was determined in that longer bridges were more economical than walls due to the existing soil conditions. Maintenance of Traffic was a major component of the design due to the urban environment. Additionally, detention and lift station designs were completed as part of the project to facilitate drainage.
