Overview
Gedeon GRC Consulting provided preliminary design services — Phases I–IV — for the bridge replacement of CR 19 over I-495, located in the Town of Brookhaven, Suffolk County, NY. The replacement gives the region the ability to construct critical bridge improvements that eliminate bridge deficiencies and improve the area’s infrastructure. The existing bridge is a four-span, multi-steel 12-girder structure with a condition rating of 4.063 (on a scale of 1 to 7) per the 2008 Biennial Inspection Report — at the time, the lowest in the region.
Scope of services
The project scope involved a traffic analysis of existing conditions and recommended methods for determining repair needs for the replacement of the bridge deck and superstructure. Bridge work included structural assessment, fatigue analysis, design for steel and concrete repair, continuity retrofit, bearings, retaining wall design, railings, lighting upgrade, asbestos removal, MPT design and related tasks. The project also involved coordination with various agencies and public outreach.
