Gridlock live: ICC, GPS, MD-97 and WWW

Dr. Gridlock just wrapped up his weekly chat, where he answers live questions from you, dear readers. Tackled this week: Crosswalk countdowns on the fritz; Washington Post Web redesign (including a more prominent traffic map); Metro closures and latenight construction; Metro’s Blue Line split; named versus numbered highways; when the ICC’s useful; and GPS issues--for Metro’s NextBus and your car on the ICC.

Check it out and submit questions for next week or browse past chats.
