Less than 30 mins depending on the time of the day.
Depends on the traffic too. If you are renting a car, make sure to stay on the inside (center) lanes. Outside lanes are toll, no cash right now, credit card only. At 495 watch out for their toll lanes too. Plan 40 to 60 minutes with light traffic.
Approximately it should be some where around 40 minutes but it depends on your time of travel, I suggest you use GPS before leaving.
I'm sorry I can't help you with your question, my best advice is to use your GPS...
