Atlanta weekend | Plan for showers at the St. Patrick’s Day Parade

Prepare to see a sea of green in Midtown this weekend.

Rain or shine — and rain is more likely — more than 20,000 people are set to attend the 134th annual St. Patrick’s Day Parade Saturday in Midtown.

The route will run parallel to Cypress and Juniper streets and perpendicular from 15th to 5th streets, according to the parade map. So beware of parade traffic.

Other travel concerns could also cause delays.

The Northwest Corridor Express Lanes project will cause travel changes along the following sections:

Traffic traveling on the eastbound collector-distributor lane of I-285 to I-75 northbound will be directed to take the I-75 southbound ramp to Cumberland Boulevard from 9 p.m. Friday to 5 a.m. Saturday, from 9 p.m. Saturday to 5 a.m. Sunday and from 9 p.m. Sunday to 5 a.m. Monday.

Traffic will then be directed to turn left on Cumberland, followed by another left to enter I-75 northbound via the ramp from Cumberland Boulevard. The I-75 southbound ramp to exit No. 259A will also be closed, and traffic will need to take exit No. 259 to access I-285 eastbound from I-75 southbound.

One lane of Delk Road will close from 9 p.m. Friday to 5 a.m. Saturday.

One northbound lane of I-75 will close between Windy Hill Road and Delk Road from 9 p.m. Friday to 5 a.m. Saturday.

One southbound lane of 1-75 will close on the exit ramp to eastbound I-285 from 10 p.m. Sunday to 5 a.m. Monday.

One northbound lane of I-75 will close between Canton Road and Barrett Parkway from 9 p.m. Sunday to 5 a.m. Monday.

One northbound lane and shoulder on I-75 will close between Jodeco Road/Flippen Road and Hudson Bridge Road/Eagles Landing Parkway from 9 p.m. Thursday to 5 a.m. Friday.

One northbound lane and one southbound lane on I-75 will close between the I-675 interchange and Mt. Zion Boulevard. The northbound lane will be closed from 9 p.m. Friday to 5 a.m. Monday. The southbound lane will be closed from 9 p.m. Friday to 7 a.m.

Two northbound lanes on I-75 will close between Delk Road and South Marietta Parkway from 7 p.m. Sunday to 5 a.m. Monday.

Rolling closures on I-75 will take place on the northbound and southbound lanes between Ga. 138 and Cumberland Boulevard from 9 p.m. Friday to 5 a.m. Sunday to allow crews to install road pavement markers. Motorists should expect multiple lane closures at a time and slow down while driving through the work zone.

Weekend to see above average temps

A warming trend that started last week in Atlanta will continue this weekend. But also prepare for afternoon showers Saturdays in metro Atlanta.

After lows of 60 degrees Saturday and 61 degrees Sunday, highs will reach 78 degrees Saturday and 73 degrees Sunday in metro Atlanta.

The best chance for rain this weekend is Saturday afternoon through Saturday night and into Sunday, Channel 2 Action News meteorologist Karen Minton said.

“So if you have outdoor plans, plan to include the rain in that scenario,” she said.

The metro area might even get thunder storms early Sunday morning.
