Thomas P. O'Neill Jr. Tunnel

Make sure you are well familiar with your directions before entering the tunnel . There are multiple entrances and exists inside the tunnel and GPS doesn't really work once inside.

There is no direct access to Logan Airport within the northbound tunnel ; airport traffic must get off at Exit 20 in the South Bay area to take Interstate 90 eastbound.

Left two lines are for driving thru . Also pray b/c people swerve into lanes when taking the curves.

There is a great view of the Zakim Bridge once you get through.

If you're planning on driving all the way through the tunnel , get in the far left lane .

Beware after midnight. That's when the cones come. And there's no way out..

Right side of tunnel has access to 93 south even though it says mass pike and Albany st

Lots of traffic

As tunnels go, this one is pretty good. Gets you where you need to go.

If you are heading southbound and you are not getting off at Purchase St (Exit 23), stay to the left. During heavy traffic times, Purchase St backs up.

Check out the cool ceiling lights.

Coolest circular thing I've ever been in

Make sure you aren't checking in while driving. Also, turn on your lights.

Don't drive under the lights, they might fall on you.

This tunnel rocks.

Hold your breath. It always smells like homeless poop.

Fart it will smell better

I left a long time ago and still stuck in the tunnel

This is hell.

Don't use the exit only lanes to pass people if there is traffic. It's just rude.
