On the east end of the bridge, there is an office door built under the main structure with a brass plaque inscribed "T. Troll".

The bridge carries traffic on US 2 above and spans the Cut River Valley, 147 feet (45 m) below.

It is a metal cantilever 12 panel rivet connected Pratt Deck Truss fixed bridge built in 1934 and rehabilitated in 1989.

Legislation passed in 2014 by the Michigan Legislature named the bridge after Heath Michael Robinson, a fallen member of the Navy SEALs who was killed on August 6, 2011 in Wardak, Afghanistan when their Chinook helicopter came under fire.

The bridge retains original standard-plan metal guardrails on the sidewalks that flank the roadway on each side.
