Lincoln and Bolton St. When police are scooting down 85, you can't see them until it's too late, when you are in their path, and in the intersection.

intersection of rte 85 and Lincoln St at Exxon station. People have no idea that if you are turning left to go towards Price Chopper you DO NOT have the right of way.

I assume that by 85 & Framingham Road, you mean trying to make the left out of Acre Bridge Road. During heavy commute times, i go down to the light at Walker even though it's out of the way I usually see cars that were in front of me still waiting.

You are probably right. I couldn't remember the name of the road just across from Kennedy's there, and Google said it was Framingham Road...

Peter's Ave (off cook lane) and Rte 20 (Boston Post Rd) is horrible in the morning or when Rte 20 is busy. Either a traffic light or no left hand turn during certain times may help.

Framingham Rd is the street across from Kennedy's, where Monti's is. Although trying to go left out of Acre Bridge is ridiculous, Framingham Rd is worse.

Turning left out of the DCU near Price Chopper onto Rt 20 is a nightmare.

Mechanic and Lincoln is only dangerous if you are attempting to go right on red. But the most dangerous intersection is where Lincoln turns into Rte 20 at Stevens St. Most people don't seem to understand who has right of way there.

Phelps St onto 20, yikes!

don't put another light on route 20! enough people cut down curtis ave, to cook lane and down to farm road to bypass 20, the traffic on cook is going to be horrid enough once all those home are built, and putting another traffic light onto rt 20 will make it even worse

How about the intersection of Mechanic , Hudson and Elm sts never know who is going to go first and then sometimes there's an ambulance trying to get to or from the hospital Never take that intersection for granted !!!!!!

It's tuff and sometimes dangerous to drive 21st century cars on 19th century roads. There are so many areas that can be a test of courage and ability to travel. To enter another viewpoint, I think anyone who has or does live on Lliberty St. can attest to the race track conditions as people speed down the street at over 40 mph (speed limit is 25) to avoid the traffic on South St. When our children went to Bigelow school they were never allowed to walk down the street by themselves because of the traffic.Many home owners have spoken to the city with no results

Coming off Concord and trying to turn left onto Rt 20 is a nightmare, and there is no alternative without a huge detour. A traffic light at Concord and Rt 20 would lower accidents, plus Cook Lane could be 2-way there and improve traffic flow.

Route 85 and Union Street is scary if you want to turn onto Union (especially travelling south on 85). There's a delayed green but no turn-only light...impossible to see cars coming if 2 cars are trying to turn from 85! Very scary.

Another badly designed and dangerous "intersection" if you want to call it that is when you're getting off the 85 connector onto 290W and trying to go South onto 495, you have to try to beat people coming out of the 495N ramp and cross over to the exit on the right.. And yes, that's technically still in Marlborough..

I swear that people who design roads never drive on them. So many stupid decisions are made. Take route 20 west near the Northborough line, who is the idiot who decided that the right lane was going away, and not the left lane (even though the left lane is the one that actually goes away)? Is it the same person who put the light right over the crest of the hill? Yeah, let's squeeze traffic out at the top of a hill and put a light there. Never had issues there until they "redesigned" it (more like screwed it up royally). I see so many problems in that area.

Ames & Forest St. They painted arrows to go left right or straight from Ames to Simarano. You can go straight from both lanes, however there are not two lanes on Simarano. There are no arrows painted at the intersection on Simarano going to Ames. Get in either lane and go which ever way you want! Brilliant!!

Phelps St. and Route 20...a nightmare at almost anytime of day.

With all due respect, this isn't even close! The intersection of Main Street, Maple Street and Hildreth is the most dangerous since there are two streets at right angles to each other (ie, Main Street and Maple Street) that appear to have the right of way!!! It's a T intersection with only one stop sign (Hildreth). I've seen a number of near accidents here from drivers who were shocked to see they were in the path of someone else who also has right of way. Someone is going to get SERIOUSLY hurt here!!!

All good points and so many different intersections! I am often concerned buy how drivers treat the stop sign inside the Hannaford plaza where the parking lot entrance crosses the end of Northboro Road East. I would say about half of all drivers going straight to exit onto Route 20 run that stop sign. While speed wouldn't be a huge factor there, I'm surprised I've never seen a fender bender.
