Road closures began early this week in Baltimore for the city’s annual Labor Day event: the Baltimore Grand Prix.

This isn’t your average marathon-day orange-cones type of street closing. The “celebration of acceleration” welcomes cars racing at speeds of up to 180 miles per hour through the heart of Baltimore, according to the organizers. Along the two-mile course, enormous reinforced fences have to be installed to ensure the safety of onlookers.

Street closures began Monday, but they escalated rapidly beginning today. All the streets won’t be reopened until 6 p.m. on September 3. Meanwhile, the Maryland DOT and race organizers insist they’re doing everything they can to minimize the impact on drivers.

But it’s a huge headache for people walking in the Charm City. Network blog Boston Streets says the event is an embarrassment on a lot of levels.

The Baltimore Grand Prix is a logistical nightmare for residents and workers. Concrete barriers and bleachers disrupt travel patterns for drivers, transit riders, cyclists, and pedestrians alike for a month leading up to the event. Trees are removed in the name of cleaner sightlines. And the noise!

To make matters worse, the company that runs the Grand Prix, Baltimore Racing Development, declared bankruptcy after its first year in 2011, and left the city of Baltimore holding the bag for some of its expenses. As part of the fallout, the company never replanted the trees as promised.

The event is run by Baltimore Mayor Stephanie Rawlings-Blake’s top campaign contributor. A source in Baltimore told Streetsblog, “Nobody within city government, or with business before city government (myself included) will trash it publicly.”
