SR 135 over Strahl Creek Bridge Rehabilitation

HWC is providing road and bridge design for this bridge rehabilitation project. The existing bridge is a 3-span continuous concrete slab bridge that is in horizontal and vertical curves along SR 135 in Brown County. The structure is deteriorated, hydraulically deficient, and has scour problems. The main scope of work is a superstructure replacement with roadway improvements to tie back into the existing superelevated roadway and safety improvements to upgrade the existing guardrail. This project will also evaluate the potential of adding a 4th span to the bridge to provide the necessary hydraulic capacity. The maintenance of traffic will utilize temporary portable signals for phased construction.

Bridge #95 Rehabilitation

This bridge rehabilitation project included the design of new semi-integral end bents, pier modifications, new structural steel beams, a concrete deck, a horizontal curve, and a super elevated roadway. This project was designed in a manner to avoid impacts to archaeological Native American sites. Right-of-way for one parcel was included in the project. The roadway embankments were widened and armored with riprap to protect against Lake Shafer wave action. Overall, this project improved all condition ratings for the bridge, geometric standards, and safety features.

Burkart Boulevard/Southern Bypass

HWC prepared the design plans for this $25 million, 3.8 mile extension of Burkart Boulevard around the southern portion of the City of Seymour. Increasing train traffic has forced the City to pursue a grade separated crossing and new alignment roadway to provide an unimpeded access route to the local hospital. HWC developed preliminary costs for the project and assisted with obtaining federal funding. Design tasks included new roadway design, roundabout intersections, drainage, a multi-use path, right-of-way assessments, coordination with impacted property owners, and overall cost estimating for the project. The project was constructed in three phases.

Bridge #227 Replacement and CR 300 East Reconstruction

HWC evaluated CR 300E from CR 1200S to CR 1250S for current safety conditions due to past accidents and public concern. The evaluation found the existing roadway geometry is equivalent to a design speed of 20 mph. In addition, Bridge 227 over Moots Creek is in the middle of this road segment and was identified for replacement through the bridge inspection. Based upon this information, White County proceeded with a 45 mph design speed for project development for the corridor to balance the factors of construction cost, construction impact to residents, safety improvements, and required no relocations.  The final project scope included 0.6 miles of reconstructed roadway, a single-span, welded-plate girder bridge using galvanized rebar and galvanized steel, retaining walls, intersection design, drainage design, waterway permits, design minimization to wetlands & Moots Creek, driveway relocations, ROW acquisition of 12 parcels, and construction inspection. The project was bid in April 2020 and completed in May 2021 with 100% local funds. 

This project utilized the unique technique and materials of galvanized structural steel, galvanized rebar, and fiber reinforcement in the concrete bridge deck and approach slabs. The previous bridge was built in 1981 and needed replacement after less than 40 years of service. The galvanized steel and rebar are anticipated to achieve the target 100-year bridge service life with limited maintenance requirements.

This project was recognized as a 2022 State Finalist for ACEC’s Engineering Excellence award.

Bridge #171 Replacement

HWC worked with White County to complete the Bridge #171 Replacement project. As part of the project, HWC completed bridge and roadway design, hydraulic analysis, waterway permitting, specifications, utility coordination, right-of-way acquisition, bidding, and construction administration services.

The existing bridge was an 82’ adjacent pre-stressed concrete box beam bridge built in 1969. The bridge had deteriorated to require a 12-ton load limit. Additionally, the roadway width was not sufficient for farm equipment, and the guardrail did not meet current standards. The new bridge included a 98’ multi-beam superstructure with integral end bents for minimized maintenance. The new bridge also included standard bridge railing, guardrail, and a 32’ wide roadway.

The project also included farm field drives for legal drain access in all four quadrants. Utilities were considered throughout the design process to minimize relocation impacts and avoid costly relocation expenses.
