GREENVILLE: A traffic mess

Sometimes it's best to ignore the GPS.
Two weeks ago I was heading to Greenville and should have just taken Route 52, but the GPS advised me Route 141 would be quicker.
Oh, how wrong it was. Apparently no-one informed Google Maps that both off-ramps from 141 onto 52 are closed due to roadwork in the Barley Mill Road area. Traffic crawled all the way from Route 48 (Lancaster Pike) to Route 100 (Montchanin Road), which is where the detour takes you.
Even DelDOT suggests avoiding the whole mess: "DelDOT is strongly recommending that motorists use alternate routes as major delays will persist into November 2018."
According to DelDOT, "the $17 million project, which began in October 2017, will replace the existing concrete roadway on this 1.4 mile section of Route 141 and on the Route 52/Kennett Pike interchange ramps, as well as replace concrete curbing, drainage, and guardrails. . . . Ramps from Route 141 north to Route 52/Kennett Pike north and south will also be closed for the duration of work to reconstruct the northbound lanes of the road. In addition, no left turns will be permitted from Route 141 north onto Barley Mill Road or from Barley Mill Road onto Route 141 north."
