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.

Bridge #516 Replacement
HWC provided design, project management, and inspection services for the Bridge #516 Replacement project in Delaware County, Indiana.
Although the project was originally scoped as a bridge rehabilitation, a full replacement was found to be the most cost effective, long-term solution due to the extensive necessary sub-structure repair work. The existing four-span bridge was replaced with a three-span, 320-foot-long bridge carrying four lanes of Tillotson Avenue over the White River. Annual average daily traffic is more than 14,000 cars per day. The design accounted for and incorporated the four utilities attached to the bridge.
The bridge was reconstructed with a full road closure rather than phased construction to provide cost savings to the County and reduce detours and delays to the traveling public. Impact to the adjoining neighborhood park was avoided, eliminating the need for a CE-4 document and reducing the project cost.

Bridge #193 Design and Inspection
HWC provided design, plan development, and part time inspection services for Bridge 193 in Vigo County. The project included complete demolition of the existing structure, new substructure and footers, new steel I-beams, a new two-lane superstructure, replacement of the existing guardrail, and paving the adjacent county road. This bridge was fully funded by Vigo County.
