Main Street Bridge

This bridge is currently undergoing rehabilitation. It is closed to vehicular traffic, but one of the sidewalks remains open to pedestrians.

Be careful in driving this bridge as it has been upgraded several times for traction problems when wet. The latest upgrade is ongoing and may have cured the problem, but take it safe driving on your mind.
