Jamestown (CSi)  The Jamestown City Engineer’s Office reports that Fourth Avenue East viaduct reopened  Monday morning about 11-O’Clock.

Sediment (mud) was deposited on the street at the underpass, from Saturday’s torrential  rain leading to the closure until the street surface was cleaned.

The slick surface had caused a male operator of a motorcycle to lose control of his bike, there.

He and his female passenger were taken to the Jamestown Regional Medical Center for treatment  of their injuries.

The accident remains under investigation.
