MJ has been providing bridge inspection for NY Thruway bridges for several decades. Our experience includes biennial bridge and sign structures along the thruway. MJ utilizes special access climbing techniques for four major span crossings.

In these photos, the MJ inspection teams performed a hands-on inspection of Castleton Bridge, a 43-span superstructure spanning the Hudson River. The MJ teams documented steel section losses and mapped the underside of the deck for deterioration. The inspection included the use of under bridge inspection units, NY Thruway work zone traffic control, and coordination with the NY Thruway and the Coast Guard.
