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.

Bridge #238 Rehabilitation

HWC worked with Hamilton County to complete the Bridge #238 Rehabilitation project. 

The project included reconstruction and widening of the bridge on Lakeshore Drive over Carmel Creek. The 75’ long, 43’ wide structure consisted of three simple spans of adjacent box beams. The bridge was completely removed down to the substructure piling.

As a result of low pile loads and the soil strata, new helical piles were used to widen the bridge. The existing pier steel shell piles were repaired and encased. 

The reconstructed bridge also includes a 14” continuous reinforced concrete slab with semi-integral end bents, integral piers, reinforced concrete approach slabs, and 5’ sidewalks on each side of the bridge. 

Approach roadway work was kept to a minimum because the low construction depth of the concrete slab superstructure allowed the existing profile grade to be maintained while improving hydraulic capacity under the bridge.

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.
