8:20 A.M. UPDATE:

Looking at our friendly neighborhood traffic cameras, it's evident that the roads in Washington are more crowded today than yesterday:

-- New York Avenue inbound (heading west from Maryland) is pretty crowded as you head into the city. It's not standstill traffic, but you can see a greater number of cars than Monday.

-- Rhode Island Avenue is also more crowded, albeit still moving.

-- K Street doesn't appear too crowded.

-- 14th Street is very packed heading southbound (to the south of K Street).

-- On 7th Street, the traffic is a bit heavier but also still moving.

-- Some of the worst traffic appears to be on Constitution Avenue at 15th Street.

7:25 A.M. UPDATE:

Traffic cameras throughout downtown Washington show that many roads remain as sparingly crowded as they were yesterday. Downtown paths like K Street have some traffic, but it's moving smoothly. On 7th and 9th streets, traffic is still light. New York Avenue inbound, heading west from Maryland, has a lot more cars and congestion, but it's still moving steadily. However, that roadway is slowly becoming more crowded, resembling a normal morning rush hour.


Tuesday is the second day of the Nuclear Security Summit. Once again, here is a roundup of the closures and detours caused by the summit:

-- Detours for 13 Metrobus routes: 70, 71, 79, G8, D4, 42, 63, 64, 80, P6, S2, S4 and X2. More information here.

-- Circulator detours. More information here.

-- Street closings and parking restrictions. More information here.

-- There's also the Metro impact (the Mount Vernon Square station will be closed). Here's the overall Sunday roundup by Dr. Gridlock.

-- And here's a live map, tracking traffic around the summit.

This blog will be updated throughout the summit, giving you real time traffic information and tips for navigating the next two days. Just remember that the while the traffic epicenter is going to be the summit, delays and headaches will ripple outward and impact commuters throughout the region. Monday's commute actually seemed relatively quiet, after so many people saw the potential gridlock and worked from home. If you are trekking out, add extra time to your commute and plan ahead. We'll do our best to help you stay as informed as possible.

A big reason for the southbound traffic jam on 14th St. at rush hour was that vehicles (presumably related to the nuclear summit) were illegally parked in travel lanes. A single white van parked in the travel lane at 14th and G caused a bottleneck that backed up traffic for several blocks.
