In Maryland's state highway system, every state-maintained road is assigned a route number in the state's primary numbering system. This is due to the fact that Maryland does not have a secondary system as do other states. As such, the system contains several routes which are either short connector roads or short former alignments of other routes. Many of these routes are listed below.
Maryland Route 344 (Chicamuxen Road) connects Maryland Route 6 with Maryland Route 224 in the western portion of Charles County. It is 2.16 miles (3.48 km) [1] long and is aligned in an east-west direction.
Maryland Route 535 (Auth Road) connects County-maintained Auth Road with the ramp to Maryland Route 5 in Prince George's County. It is approximately 0.16 miles (0.26 km) [5] long and is aligned in an east-west direction.
Maryland Route 625 is a spur route off of MD 5 that takes Route 5's old alignment through the center of Hughesville, Charles County. Route 5 was routed around Hughesville via a bypass to alleviate a major bottleneck for through traffic traveling from the surrounding counties, as the intersection of Route 5 and MD 231 is essentially a crossroads for the Southern Maryland region. Route 231 heads east into Calvert County, while north on Route 5/Route 625 heads to Waldorf, Charles County and south leads to St. Mary's County. It has one intersection in the center of Hughesville with Route 231 via a series of two roundabouts and it is 1.36 miles (2.19 km) [2] long.
