Semi gets stuck at RR Bridge 12'10"
NEED WARNING SIGNS AT E GRAND AVE!!!!
No passage for trucks over 12'.
The only other through street is Hemingway which has 12' 3" Clarence.
Drivers from out of the area are following GPS which takes them up quintipiac. How do you get GPS to note the clearance and the clearance and not allow big rigs to go that way. New Haven needs to put up signs at grand Avenue..
