| In 1995, U.S. 222 was removed from Susquehanna River Road in an effort to reduce traffic on a fairly narrow and winding road with a low clearance railroad bridge at Port Deposit.

| U.S. 1 approaches MD 273, which follows Rising Sun Road east through Rising Sun, Calvert, Fair Hill, and Appleton, then changes into SR 273 upon entering the First State. This is an excellent route into Newark, Delaware, without rejoining Interstate 95 or following slower U.S. 40/Pulaski Highway through Elkton. Of course, MD 273 is also part of a longer alternate route for avoiding the Susquehanna River Bridge tolls on both routes and the Delaware Turnpike toll on Interstate 95 near Newark. 06/25/10 |
