ConstructConnect
ConstructConnect is maintaining an interactive map updated with the "essential" or other status of construction in the 50 U.S. states.
Find out which states are restarting work, which areas are subject only to local rulings and where local jurisdictions and state DOTs have imposed their own construction restrictions.
There's a link to a similar map of Canadian provinces.
You'll also find a link to a database of more than 4,000 delayed construction projects (as of April 30).
