Interstate 84 Auxiliary Lane Addition, CTDOT

I-84 is a major interstate highway between Pennsylvania and Massachusetts. It traverses Connecticut from the southwest corner to the northeast border, which gives the state the highway’s longest stretch of the corridor. BL Companies is providing design services to the Connecticut Department of Transportation for the proposed addition of auxiliary lanes along I-84 in West Hartford. This project includes the replacement and widening of the superstructures for the I-84 eastbound and westbound bridges over Berkshire Road and I-84 westbound over Ridgewood Road. BL Companies also performed detailed bridge inspections for the evaluation of the existing structures.

BL Companies is responsible for providing wetland delineation, survey, subsurface utility exploration, geotechnical engineering, highway design, drainage design, structural design, permitting, lighting design, and the review of shop drawings. BL Companies is also responsible for obtaining Connecticut Department of Environmental Protection Inland Wetlands and Watercourses, Stormwater Discharge Permits and Flood Management Certification Approval.

BL Companies survey tasks have included the update of CTDOT aerial maps, research of utility company records, field surveying of utility locations, delineation of inland wetlands, horizontal and vertical survey control, detailed bridge surveys with horizontal and vertical location of abutments, haunches, seats, decks, stakeout and mapping of test pits and soil borings as well as ground topographic survey/cross-sections.
