Power restored in Uniondale after utility pole crash that seriously injured driver

A serious single-vehicle crash early Monday morning in Uniondale knocked down a utility pole and caused area residents to lose power, police said.

The incident was one of two that forced traffic to be diverted overnight Sunday into Monday in Nassau County, police said. 

Nassau police said the Uniondale crash occurred on Jerusalem Avenue, just west of Uniondale Avenue, at about 6:30 a.m.

The driver, who was the lone occupant in the vehicle, was transported to a hospital with serious injuries, police said.

The crash closed Jerusalem Avenue between Greengrove and Edgemere avenues. The closure is in the vicinity of St. Martha's Catholic Church.

PSEG Long Island said the incident also left almost 700 area customers without power, but an update on its outage map website indicated those outages were restored.

Patrol units were still on the scene as of 10 a.m. and estimated the road would remain closed until all repairs could be completed, asking that motorists avoid the area and find an alternate route.

Meanwhile, police said emergency crews from Liberty Utilities were still working to fix a water main break near the intersection of Long Beach Road and Daly Boulevard in Oceanside.

Police said the break was reported at 5:23 p.m. Sunday and flooding had been contained to one southbound lane on Long Beach Road Monday.

Police were still on scene at 10 a.m. Monday, diverting traffic
