Just in case subway riders haven't gotten a taste of Casey Arborway construction traffic, the T will be putting Orange Line passengers in shuttle buses this Saturday and Sunday, and again next weekend. The shuttle buses will be running so track and signal work can be done. The closures are in both directions from Ruggles to Forest Hills. Casey construction hours generally run through about 3:30 p.m. on Saturdays, though night work is slated to begin at 8 p.m. on Sunday, June 14, the last scheduled day of bus replacement service. For more on the subway closures, please visit the T's Website.
