This fast-track project was completed four weeks ahead of its 36 week contract schedule during one of the worst winters in Connecticut history. As many as 160 O&G personnel and 80 pieces of heavy equipment worked through a record seasonal snowfall of 115.2 inches without missing a single day. The project was constructed in phases to maintain the heavy traffic on Route 2A, resulting in minimal working zones.
The maintenance of traffic on Route 2A at the rock cut of the westbound on/off ramps limited the actual blasting and cleaning of Route 2A to two, 12-minute windows per day. The project presented many environmental challenges since nearly seventy-five percent of the work was along wetlands. Crews were constantly checking erosion control safeguards and replacing or upgrading them as conditions demanded. While work was in progress, O&G constructed a rock crushing plant on site to utilize the excavated material as a subbase for the new construction. This processing operation handled over 230,000 tons of material.
