New York Today: Gridlock Alert

Ruth Fremson/The New York Times

Good morning and happier travels: Metro-North’s Hudson Line is running again.

But the evening commute may still be a slog â€" Wednesday is the first of seven Gridlock Alert Days this month. Here’s what you need to know:

Don’t be fooled by the twinkling lights and rosy faces.

All around the Christmas Tree at Rockefeller Center, which will be lighted tonight between 7 and 9, people will be feeling miserable.

They’ll be the ones stuck in traffic.

It will start in the afternoon, when the four blocks around Rockefeller Center will be closed to cars and filled with barricades.

As Fifth and Sixth Avenues shut down, traffic will be pushed from avenue to avenue.

With 48th to 52nd Streets closed, the 40s and 50s will be virtually impassable.

In 1982, the city traffic commissioner Samuel I. Schwartz, now known as Gridlock Sam, released a list of the days with the heaviest traffic.

The city has recognized Gridlock Alert Days ever since.

The list has evolved over the years, but because of the holidays, December has always been bad.

People shop on Thursdays and Fridays. On Wednesdays around Christmas, matinees are the cause.

Our advice: To avoid frustration today, walk or take the subway.

If you must drive, pack a 45-minute cushion.

WEATHER

Reminiscent of days of old: yesterday. Sun, clouds, high around 54.

But clouding over tonight, with a 50-50 chance of light rain.

COMMUTE

Subways: Check latest status.

Rails: Metro-North’s Hudson line is back in service, with almost all scheduled trains running. But only on one track, so expect congestion delays of up to 15 minutes. See details.

Fans of the temporary shuttle bus from the Yonkers train station to the 1 subway line in the Bronx will find it still operational.

Check L.I.R.R., Metro-North or New Jersey Transit status.

Roads: Check traffic map or radio report on the 1s.

Alternate-side parking is in effect till Christmas.
