In 2010, a new bridge over Chincoteague Channel into Chincoteague opened, moving the eastern termius to the Main St/Maddox Blvd intersection.  The old 1940 bridge was demolished in 2011.
Improvements:  Fully paved upon designation; no multilane segments exist.
Posting:  Fully posted except not at its eastern end.
As late as the mid-1990s there was a white border sign in Chincoteague routing you to the south to stay on 175 once on the island.
Multiplexes:  None
Legislative names:  John B. Whealton Memorial Causeway (entire route) since 3-15-44.
Other names:  Chincoteague Rd
Scenic Byway:  No segments
Comment:  VA 175 has a long marsh causeway connecting Chincoteague to the mainland.
The old bridge to Chincoteague Island was a fairly picturesque truss drawspan, but removing it eliminated direct access between Chincoteague Island and those that lived on Marsh Island.  VDOT had to build a connector bridge from Marsh Island to the new VA 175 bridge as part of the overall project. This stub segment is now OSR 175.
