interchange opened at Bradley Avenue. Later in 1994, the Highbury Avenue interchange and overpass at Highway401 was reconstructed. The reconstruction led to the existing cloverleaf being converted to a parclo configuration with traffic lights. Highbury Avenue was extended south to St. Thomas circa 1999, along what was known as Hubrey Side Road within London, and Radio Road within Elgin County. Future Work is currently underway to replace the bridge over the Thames River, which as of 2021 is 57 years old. Following completion, a million contract is set to begin in late 2022 to rebuild the route south of the bridge to Highway401. A cost–benefit analysis is being conducted to determine if a concrete or asphalt surface is better suited for the road.
