The 36th running of the Richard S. Caliguiri City of Pittsburgh Great Race will cause road closures and transit detours Sunday in Downtown, Oakland and Squirrel Hill.
Race organizers are urging the 15,500 registered runners to park Downtown and take special bus shuttles to the starting lines of the 5K and 10K events.
Shuttles will leave from the Gateway T station at Stanwix Street between Penn and Liberty avenues from 6:15-7:15 a.m. for the 5K race and 7:15-8:45 a.m. for the 10K run.
The buses will run again from there from 9:30 a.m. to 12:30 p.m. for runners who need to return to the area of the starting lines.
No animals except guide animals are allowed on the buses.
On-street parking will be hard to find near the start lines but some Oakland garages are near the 5K starting line.
The 5K race begins at Fifth Avenue and Atwood Street in Oakland at 8 a.m.; the 10K run begins at Beechwood Boulevard near Frick Park at 9:30 a.m.
Road closures are expected at various times starting at 5:30 a.m. and concluding by 1 p.m. on sections of Beechwood, Dallas Avenue, Forbes Avenue, Morewood Avenue and Fifth Avenue, the Boulevard of the Allies (including its Oakland entrance ramp) from Fifth Avenue to Commonwealth Place; Wood Street from Allies to Fort Pitt Boulevard; Fort Pitt Boulevard from Wood Street to Commonwealth Place; Stanwix Street from Fort Pitt to Allies, and Commonwealth Place from Allies to Fort Duquesne Boulevard, including the blockage of Fort Pitt Bridge ramps at Liberty. Gateway Center in its entirety will be closed to traffic.
More than 30 Port Authority bus routes will be detoured. Details are posted on the authority's website, www.portauthority.org.
Also, Red Line rail service will be detoured because of construction at the Dormont Avenue grade crossing. Red Line trains will operate via the Blue Line between Overbrook Junction-Willow and South Hills Junction. A rail shuttle will operate between Overbrook Junction and Dormont. Bus shuttles will operate between Dormont and Fallowfield. Another rail shuttle will connect Shiras and South Hills Junction.
One other complication for runners and spectators headed Downtown: One lane will be closed in both directions on the Liberty Bridge until 6 a.m. Monday. A contractor will remove sections of pavement to inspect the deck structure.
