Obstacle course weekend

From May 1-4, streets in Richmond’s downtown and Fan District areas will be closed and traffic patterns will be radically altered because of the USA Cycling Collegiate Road National Championships. Traffic advisories and street-closure maps are available from the presenting organization, Richmond2015, at www.richmond2015.com

The major classical-music events affected by street closures are:

-- The Richmond Symphony’s Rush Hour Concert, 6:30 p.m. May 1 at Richmond CenterStage, Sixth and Grace streets. Closures will begin at 7 p.m. on East Broad Street between Third and Seventh streets; Fifth Street between East Marshall and East Grace streets; and Third Street between East Clay and East Broad streets. Park south of Grace Street to avoid the closures and the risk of having your vehicle towed.

-- The Rennolds Chamber Concerts program by the American String Quartet with violist Roberto Díaz and cellist Andrés Díaz, 8 p.m. May 3 at Virginia Commonwealth University’s Singleton Arts Center, Park Avenue at Harrison Street. Street closures on that day are between Marshall, Main, First and Seventh streets, well to the east of the Singleton Center; the closures are scheduled to end at 7 p.m. Some traffic congestion/confusion may persist around the center of the city, however, so allow extra time to get to the concert. Driving home afterward shouldn’t be a problem.
