Alexandria’s DASH bus system will beef up mid-day service Tuesday, with additional buses running starting at 11:30 a.m. until the beginning of the peak afternoon period.

The AT3 and AT4 buses that serve the Pentagon will run every 30 minutes. The buses from Mark Center Station to the King Street-Old TownMetro station will also run every 30 minutes.

Allyson M. Teevan, a spokeswoman for DASH, said the agency wants to make sure that there are more buses available to handle early rush hour Tuesday as a result of the government shutdown.

Ride-On buses would not have any additional mid-day service, said Montgomery County spokeswoman Donna Bigler.

Metro said Tuesday that it will not run rush hour-level service mid-day even with many workers leaving for the shutdown.
