west of the Calvert Cliffs Nuclear Power Plant. Another section of MD 765, Saw Mill Road, parallels the divided highway between Calvert Cliffs Parkway, which leads to the power station, and Flag Pond Parkway, which leads to Flag Ponds Nature Park. After crossing Quaker Swamp, also known as Woodland Branch of St. Leonard Creek, MD 2-4 enters the community of St. Leonard and is paralleled to the east by another segment of MD 765, St. Leonard Road. At the intersection with Ball Road/Calvert Beach Road in St. Leonard, the road passes east of a park and ride lot serving MTA Maryland commuter buses. Calvert Beach Road heads east to serve Calvert Beach. The highway intersects Western Shores Boulevard, which provide access to Long Beach, respectively. In Port Republic, MD 2-4 curve west at MD 509 (Governor Run Road) and has a dual intersection with MD 765 and MD 264 (Broomes Island Road). The junction with MD 765 is a right-in/right-out intersection with northbound MD 2-4; the MD 264 intersection is a directional crossover. MD 2-4 meets the eastern end of MD 506 (Sixes Road) and curves north toward the unincorporated town center of Prince Frederick. MD 765 (Main Street) splits to the northbound side of the main highway shortly before the highways cross Parker Creek, and MD 2-4 expands to six lanes ahead of its intersection with MD 231, which heads west as Hallowing Point Road and east as Church Street toward the Calvert County courthouse and offices. Further north, the highway receives the north end of MD 765. The routes leave Prince Frederick after their junction with MD 402 (Dares Beach Road) and the roadway reduces to four lanes before passing west of Calvert Health Medical Center. MD 2-4 cross Hunting Creek immediately after their directional crossover intersection with MD 263 (Plum Point Road). The highway parallels the loop of MD 524 (Old Town Road), which leads to MD 521, through Huntingtown. A park and ride lot is located southwest of the intersection with the southern terminus of MD 524. Within Huntingtown, the divided highway passes west of Huntingtown High School. From Huntingtown, the divided highway continues straight north to the split of MD 2 and MD 4 at a directional crossover intersection in Sunderland. Sunderland to Suitland MD 4 continues northwest as four-lane divided Southern Maryland Boulevard while MD 2 heads northeast as Solomons Island Road toward Annapolis.
