Are two-way bicycle lanes allowed on highways?

Bicycle lanes are to be located on both sides of the road on two-way streets. Two-way bicycle lanes on one side of the street create hazardous conditions and are not recommended.

Riding a bicycle against the traffic flow is against the law in New York and is discussed
in the Vehicle and Traffic
Law Section 1234(a)

Upon all roadways, any bicycle or in-line skate shall be driven either on a usable bicycle or in-line skate lane or, if a usable bicycle or in-line skate lane has  not  been provided, near the right-hand curb or edge of the roadway or upon a usable right-hand  shoulder in such a manner as to prevent undue interference with the flow of traffic except when preparing for a left turn or when reasonably necessary to avoid conditions that would make it unsafe to continue along near the right-hand curb or edge.
