O&G Industries Leads $54.6M I-84 Safety, Operational Improvement Job

O&G Website; February 25, 2021

The Connecticut Department of Transportation's (CTDOT) $54.6 million I-84 Safety and Operational Improvements project in West Hartford, awarded to O&G Industries Inc., is based upon the mitigation of traffic congestion and safety concerns that can arise in heavy traffic situations.

This two-stage project, financed by the state and designed by BL Companies, started in March 2020 and should be completed in summer 2023. Additional parties involved in the project include Urban Engineers Inc., hired as the construction engineering and inspection consultant.

The project runs west and east along I-84. From the west, it begins at the Farmington/West Hartford town line and ends at the Park Road on-ramp and from the east and 500 ft. east of the Ridgewood Road overpass and extends 200 ft. east of the Mayflower overpass.

Ghazi Alsaqri, CTDOT's project engineer, addressed the initiative's benefits and positive impacts.

"The existing traffic volume within the project limits is at or near capacity, and combined with closely spaced interchanges, results in congestion and weaving concerns on this section," he said. "A review of the three-year crash data between 2012 and 2014 revealed a total of 159 crashes with 48 injuries and one fatality on I-84 WB, and a total of 202 crashes with 90 injuries and one fatality on I-84 EB. The crashes seen most prominently in this time period — rear endings, sideswiping, fixed-object crashes — are indicative of issues related to congestion and vehicle weaving maneuvers.

"The region has grown and with that, the foundations built previously are no longer feasible for the increased volume," he added. "I-84 was constructed in the early 1960s to support regional mobility and commerce; and as the region has grown over the past 60 years, so has daily traffic. Upon its completion, the sections being improved will achieve project goals of increased commuter safety, local and regional commerce and freight mobility."

An additional lane is being added on I-84 WB between Exits 39A and 43, which extends 9,500 ft. Additionally, for the I-84 EB direction, a lane will be added between Exit 40 and 41, which extends 2,800 ft. The lane additions in both directions are feasible via the replacement of the Berkshire Road bridges to accommodate them.   Read More>>>
