For anyone going to the MMMSC launch on the 15th, Hubbard Road is closed approaching the field from the south at the point where they have had the traffic lights and single lane road. Approaching from the north will be your only option.
Last year, Guy Wadsworth posted the following directions to avoid the construction in Somersworth, NH; they will work for this situation, too:
Here are Guy's alternate directions:
If you normally head up the Spaulding Turnpike (may involve tolls)
Continue on up the Spaulding Turnpike (Rt 16) to exit 16, the Rt 11/Rt 202 exit. Keep bearing right towards Sanford ME and Rt 202 east.
Follow Rt 202 east to the NH/ME border. There will be a Cumberland Farms on your right at the four way stop, just before the border.
Continue on through the four way stop on Rt 202 East until you see a Mobil Station on your right. You will have traveled about 3.5 miles
from the Spaulding Turnpike. There is a traffic light at the corner that the Mobil Station is on. Turn right at the traffic light on to
Hubbard Rd. The Tuckahoe Turf Farm will be on your left (2.9 miles).
If you want to travel on Rt 125 from Mass:
Head north on Rt 125 through Epping, Lee, Barrington and Gonic until you reach Rt 16, the Spaulding Turnpike. Stay to the far right,
going under Rt 16 and then on to Rt 16 north.
Continue on up the Spaulding Turnpike (Rt 16) to exit 16, the Rt 11/Rt 202 exit. Keep bearing right towards Sanford ME and Rt 202 east.
Follow Rt 202 east to the NH/ME border. There will be a Cumberland Farms on your right at the four way stop, just before the border.
Continue on through the four way stop on Rt 202 East until you see a Mobil Station on your right. You will have traveled about 3.5 miles
from the Spaulding Turnpike. There is a traffic light at the corner that the Mobil Station is on. Turn right at the traffic light on to
Hubbard Rd. The Tuckahoe Turf Farm will be on your left (2.9 miles).
