- Streets & Roads
- Tapawingo Drive, West Lafayette, Indiana
Client: City of West Lafayette
 The need to connect people and places drives most transportation projects and this new 4-lane road from State Road 26 and US 231 does exactly that. The project, intended to alleviate congestion and open the area for future development, also features a paved walking and biking trail with greenspace and lighting to enhance access for new residential development to retail and restaurants, as well as nearby Purdue University.
- Illinois 160 from Deal Street to Lemon Street, Highland, Illinois
Client: Illinois Department of Transportation
Prepared final design plans and construction bid documents for resurfacing of 1 mile of Illinois 160 from just west of Deal Street to Lemon Street, along with improvements to the Illinois 160/Deal Street intersection. The scope of work included milling and resurfacing the existing pavement, pavement patching, curb repair, and installation of decorative hot-mix asphalt stamped crosswalks. Pavement cross-slope deficiencies will also be addressed as part of the project. Improvements at the Illinois 160/Deal Street intersection consist of widening the existing pavement and constructing new combination concrete curb and gutter to add a 12-foot-wide, left-turn lane for westbound traffic along Illinois 160 and to improve the radius returns at the intersection. The intersection work also required the relocation of an existing 84-inch storm sewer and the design and construction of a large junction chamber.
Highway/Freeway- IL 141, New Haven, Illinois
Client: Illinois Department of Transportaton
This Phase II engineering project involved right-of-way plans, contract plans, special provisions and estimates for the rehabilitation of IL 141 (FAP 877) from New Haven to 2 miles east of New Haven. Work included land surveys, property descriptions, and the preparation of plats and plans; ground field surveys (DTM); highway drainage design; and erosion control plans. This project also included flattening and stabilizing existing slopes, asphalt and aggregate shoulders, creating an erosion control plan, and extending box culverts.
- US 41 Design-Build, Knox County, Indiana
Client: Indiana Department of Transportation
 This road reconstruction stretches from State Road 241 to the US 50 Interchange. Retaining walls were used to lower the profile grade of US 41 near the Hart Street and State Road 61 underpasses in order to increase the vertical clearance to a minimum of 16 feet. Roadside safety issues were addressed as part of the project. An Engineer’s Report was developed after design and construction to identify the areas that were substandard and could not be addressed because of the limits of the existing right-of-way.
Interchanges- Old Chain of Rocks Canal Bridge, Madison Illinois
Client: Madison County
 This Pennsylvania Petit Through Truss bridge spans the Chain of Rocks Canal, built in 1949, to allow large river barges to by-pass a treacherous section of the Mississippi River. When asked to assess its structural integrity and condition, BLA engineers and inspectors used an aerial manlift, under-bridge inspection truck, and free-style climbing to access the various components of the bridge. As a result of the inspection, recommendations were provided to prolong the life of the bridge and maintain its continued safety for the vehicle, pedestrian, and bike traffic using it today.
- I-465 Interchange Reconstruction, Indianapolis, Indiana
Client: Indiana Department of Transportation
 As many as 178,000 vehicles a day pass over this busy section of I-465, making it one of the most heavily traveled locations in the state of Indiana. This high demand prompted the redesign of the interchange to include eight lanes of main lane with as many as of eight additional lanes supporting the ramps. A key challenge for BLA engineers on this $75 million project was developing a design and construction phasing that would minimize disruption to the many travelers who depend on the interchange daily.
Design for reconstruction involved the reconfiguration of a complex collector-distributor interchange with 10 bridge structure replacements or rehabilitations. All mainline pavements were replaced and ramps reconstructed while maintaining traffic. During the development of the construction plans for the second phase, it was determined that the contractor could have difficulty in completing all the work in one construction season, so BLA developed a scenario where a large amount of work could be done at one time without affecting the overall movement of traffic along I-465.
Trails- Pigeon Creek Greenway, Evansville, Indiana
Client: Evansville Department of Parks and Recreation
 Pigeon Creek Greenway Passage is a proposed 42-mile system of pedestrian and bicycle trails linking residential, commercial, institutional, and recreational facilities around the City of Evansville. BLA is responsible for the initial development of Phase 3, Section C, a 3.2-mile section that will ultimately connect the terminus of Section 3B with the previously constructed phases. Floodplain issues, difficult terrain crossings, safety measures related to traffic, and enhancement measures were among the many design features of this project.
Largely located on the levee system, this portion of the trail will offer safe travel from the downtown area to Garvin Park, Lamasco Park, Golfmoor Ball Fields, as well as the newly developed Skate Park. In addition, this will also allow for connection of the Evansville waterfront area to the other parks in the city. The historic Ohio Street Bridge, which was to be renovated, will be incorporated into the trail and renamed the Joan Marchand Overlook after a former local historian. Across the street from the Joan Marchand Overlook where a scrap metal yard once existed, is a park where Evansville's industrial history is featured along with a trail head and park amenities such as canoe launch ramps, benches and landscaping.
- Ouabache State Park Bike Trail Design, Wells County, Indiana
Client: Indiana Department of Natural Resources (DNR)
Indiana DNR retained BLA to develop the location and design of a bicycle trail for the Ouabache State Park. Previously, a bicycle trail existed from Bluffton to a mile west of the park. Indiana DNR wished to extend this trail through the park along the Wabash River to a point near the east side of the park and then engage a service road which ran through the park. This facility allowed hikers and bicyclists to travel all the way from Bluffton to the state park and within the state park to the camping and recreational areas. The project length was 4.2 miles (22,500 feet).
Traffic Studies- Safety Study for the Intersection of IL Route 32 & Bruce Findlay Road, Moultrie County, Illinois
Client: Illinois Department of Transportation
Conducted a safety study to investigate potential causes of accidents and evaluate potential improvements to reduce accidents at the intersection of IL Route 32 and Bruce Findlay Road. The scope of work included data collection, traffic signal warrant analysis, multi-way stop warrant analysis, an evaluation of the existing roadway network, an analysis of the existing roadway network with future roadway improvements, a crash analysis, and recommendations for improvements to the intersection.
