DelDOT finally posted the
workshop materials from the SR 1 - Corridor Capacity Preservation Program meetings from early this month, detailing plans to convert SR 1 between Dover and Five Points into an expressway (sort of... every link is broken except for the
GIS page with the full plans).
Highlights include preliminary plans for a number of new grade separations, new frontage roads, intersection and driveway removals, master plans for Little Heaven and Frederica, and the addition of a third lane between Dover and the US 113 split in Milford. Curiously the new third lane isn't depicted as extending through Dover using the existing roadbed that's striped as a wide left shoulder, though I imagine that's due to anything north of Dover being out of the project's scope.
