Baltimore officials are warning of heavy traffic Saturday as the city hosts the Maryland Cycling Classic, an Orioles home game marking a Cal Ripken milestone and a sold-out Benson Boone concert at CFG Bank Arena.

“This is a major city with major city events. There will be traffic,” Mayor Brandon Scott said at a news conference Wednesday, encouraging drivers to consult the Waze app before making their way downtown this weekend.

Some lane closures along the 17.9-mile course for the Maryland Cycling Classic have already started with more beginning Friday evening. During the race Saturday, the course will be closed to vehicles. There will also be parking restrictions along the entire race route and commercial vehicle restrictions on Saturday.

In addition to the events this weekend, there will also be a MetroLink Subway shutdown for ongoing testing, according to an alert from the Maryland Transit Administration. Subway stations will be closed from 7 p.m on Friday until 6 a.m. on Saturday, and then again from 6 a.m. on Sunday until 5 a.m. on Monday.

MTA Administrator Holly Arnold said in a post on social media that Metro stations will be operating on Saturday and are an option for people looking to get around the city during the Maryland Cycling Classic. Shuttle bus service will be in place during the times the Metro is closed this weekend.

Maryland Cycling Classic

The Saturday event includes professional men’s and women’s races, with the women’s race starting at 8:30 a.m. and the men’s at 12:30 p.m.

Both races will be held on a circuit course through the city that starts at Harbor Point’s Central Plaza, goes over the cobblestones of Fells Point and around Patterson Park before coming back to Mount Vernon, winding its way up Falls Road to Northern Parkway, and then eventually coming back down along St. Paul Street. The races end on East Pratt Street along the Inner Harbor.

Lanes along Pratt Street between Beluga Boulevard and President Street closed Thursday evening. Pratt Street will be fully closed from South Gay to President streets starting at 11 p.m. Friday through midnight Sunday.

Streets along the race circuit will be closed Saturday morning until around 6 p.m. There will be detours and parking restrictions in place, as well as commercial vehicle restrictions. The Baltimore Police Department will also manage rolling closures along the race route throughout Saturday.

The following roads and lanes will be closed:

• Market Place from East Pratt to Lombard starting Friday evening through midnight Sunday;
• Jones Falls Expressway/I-83 South at Maryland Avenue on Saturday from 3 a.m. to 8 p.m.;
• The intersection of Dock Street at Central Avenue, from 5 a.m. Saturday through midnight Sunday;
• The intersection of Dock and Wills streets, from 5 a.m. Saturday through midnight Sunday.

Check the Baltimore City Department of Transportation‘s website for a comprehensive list of streets along the race circuit that will be closed Saturday. The city also has an interactive road closure dashboard for the race.

MTA bus service in Baltimore will also detour around the road closures on Saturday, and MDOT warned riders should plan for extra travel time. According to MTA, the routes impacted include:

• CityLink: Blue, Brown, Gold, Green, Lime, Navy, Orange, Pink, Purple, Red, Silver, and Yellow
• LocalLink: 21, 22, 28, 30, 33, 51, 53, 54, 56, 65, 67, 71, 76, 78, 80, 91, and 94

Charm City Circulator routes will also be modified on Saturday around the race course until 8 p.m., according to the Department of Transportation.

Orioles game and Benson Boone concert

The Orioles host the Dodgers starting at 7:05 p.m. Saturday, with the club marking the 30th anniversary of Ripken playing in his 2,131st consecutive game, breaking the record previously held by Lou Gehrig.

Doors for the Benson Boone “American Heart” tour concert at CFG Bank Arena open at 6:30 p.m. and the event starts at 8 p.m.

Boone concert and Orioles game attendees should use Interstate 395 to and from the venues, the department said.

“We want folks to enjoy themselves at the game, at the concert, at the race, but understand there will be significant traffic impact,” Scott said.
