Sikorsky Traffic Improvement Study
AI was charged with developing a solution to improve traffic on Route 110 near the Sikorsky plant and the road network within the Stratford manufacturing facility due to significant congestion between the facility roadways, Route 110 and the Route 110/Route 15 Interchange ramps around the plant during the shift changes. There are three access driveways into the Sikorsky manufacturing facility off Route 110. Additionally, just south of the facility, there are the Route 15/110 interchange ramps. A traffic analysis was performed for a 6000' section of Route 110 and for the roadway network within the facility. Traffic counts with turning movements were taken within the study area and existing Level of Service (LOS) was calculated for roadway and signals. A study of alternate access configurations was developed and analyzed to determine the roadway LOS for each alternative. Part of the analysis included environmental impact determination and cost benefit analysis. The study found that relocation of the South Gate Access Drive by 170' to develop a 4-way intersection at Oronoque Lane with Route 110 was desirable. This eliminated a signal between the Route 15 southbound ramps and Oronoque Lane which reduced delays at this intersection and within the facility. ConnDOT concurred with the findings and supported this change to the state highway. The Stratford Traffic Commission also accepted the recommendation. AI prepared the preliminary and final design and contract documents for the Route 110 reconstruction. A separate design of the facility driveway relocation and 25 acres of site improvements were also prepared. A new design for the 2,400 space parking area to the south of the facility was developed.
