Construction Begins on Major A34, Colchester Interchange Projects

Major construction projects are underway to improve traffic flow and safety at key highway junctions in both Vermont and Oxfordshire. In Colchester, Vermont, the I-89 Exit 16 intersection is undergoing a multi-year overhaul featuring a new diverging diamond design intended to reduce congestion by summer 2026, though local businesses currently report sales losses of 10-20% due to construction disruptions. Meanwhile, in Oxfordshire, the Lodge Hill interchange on the A34 is being upgraded with the addition of new south-facing slip roads, a dumbbell junction, and enhanced pedestrian and cycling facilities. This project, fully funded and managed by Oxfordshire County Council and expected to finish by the end of 2026, aims to increase junction capacity, shorten journey times, and support the development of over 1,000 new homes in Abingdon by 2031. Both projects involve phased construction with temporary traffic controls in place to minimize disruption while preparing for long-term improvements. Officials urge patience from the public, emphasizing the benefits these upgrades will bring to traffic congestion, safety, and regional economic growth once completed.
