What is this I do not yet know. It was on the south side of the bridge from the Paul H. Smith plaque

  1. H20-S16-44 (now called HS20-44) means the maximum axle load is 32 K on a single axle or 16 K (the middle number) on *each* of two axles in tandem.“HS” refers to the type of vehicles a bridge or highway can accommodate; “20” refers to the loading specification of the bridge; “44” indicates the year the specification was adopted. HS20-44 capacity means that the bridge or highway is able to safely accommodate 3-4 axle vehicles, such as a large semi-truck and trailer. Seems to be the standard in bridge design.
