The Yale Shuttle is again being re-routed because of poor road conditions on Prospect Street caused by the wintry weather, according to an e-mail from Ed Bebyn, manager of Yale Parking and Transit.

The Red line is currently turning around at 344 Winchester Avenue and returning via Winchester. The Blue line is going up Sachem Street then turning on Sachem to go up Whitney Avenue to East Rock Road and returning via Whitney.

UPDATE 3:51 p.m.: The Red and Blue lines were set to return to normal service at 2 p.m. according to a message on the Yale Transit website.
