Grid Modernization

HWC provided design and construction inspection services for the $1.9 million Grid Modernization Project in the Downtown Corridor of New Albany, Indiana.

The project began with a conceptual study that evaluated past recommendations, identified three options for the one-way to two-way grid modernization, and identified three complementary projects for the downtown corridor. HWC studied options for grid corridor modernization, and the chosen option included converting Spring, Market, Elm, Pearl, and Bank streets to two-way traffic. This option manages vehicle patterns, improves access to downtown businesses, calms traffic, improves pedestrian safety, provides bike lanes, and enhances the economic vitality of downtown businesses.

The project included the modernization of 15 traffic signals through the project corridor and upgrades pavement markings and signage for two-way traffic. The identified complementary projects include downtown streetscape improvements, one-way to two-way conversions west of State Street, and a downtown pedestrian bicycle plan.

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 #97 Replacement

After a 15-year closure, a historic, single-lane, single-span steel truss bridge was removed and salvaged to make way for the new, two-lane, three-span modernized bridge over Killbuck Creek in Madison County, Indiana. The existing channel of Killbuck Creek was realigned in order to reduce a large skewed crossing to a 30 degree skewed crossing to help alleviate nearby flooding. Additionally, the existing retaining wall was reconstructed and lengthened to protect the Fork Creek tributary that runs along the eastbound lane. This project improved the overall hydraulic performance, enhanced vehicular safety, reconnected sections of Madison County, and provided a more direct route for nearby residents.
