• Removal could cost more than repairs

• Businesses suffering

• Permanent detour around  Main Street

• Hydraulic Opening not an issue

Repair of the Existing Bridge

• Overall Repairs to Bridge where feasible 

• Cost of repairs 

• Repairs could be made by County

• Hydraulic opening could be increased by dredging stream bed to original elevation

It’s official – Bridge to be RepairedPhoenicia's Bridge Street Bridge over the Esopus Creek, knocked out of commission by the Irene floods last summer and thought to be un‐fixable, will be put back in service after all, Ulster County officials say.

A press release issued today by the office of Mike Hein, Ulster County executive:

Phoenicia, NY – County Executive Mike Hein is extremely pleased to announce that a preliminary assessment by the independent engineering firm Peak Engineering indicates that the damage caused to the Bridge Street Bridge in Phoenicia by Hurricane Irene and Tropical Storm Lee is not irreparable as originally thought.  As such, the Ulster County Bridge Crew is expected to be able to provide the necessary repairs in order to reopen this vital link to the Hamlet of Phoenicia.

According to County Executive Hein, “Hurricane Irene was the worst natural disaster in our County’s history, causing over $15 million in damages to County infrastructure, “I fully recognize the importance of this bridge to the business district and the citizens of Phoenicia.  .  Though there is an extensive amount of work to be done on the Bridge Street Bridge, we look forward to celebrating its reopening by July 4th weekend.”
