The Keystone Wye timber arch bridge on Hwy 16 and 16A is going through an extensive renovation. The concrete decks are being removed and replaced with a timber deck and asphalt overlay. Additionally, the bridge beams will be treated to prevent rot and the concrete supports will be patched and sealed. Project benefits include extending the life of the existing bridge for another 50+ years.
