Rainier Brentwood Cottage City Colmar Manor	US 1 · Rhode Island Ave., Baltimore Ave., Baltimore-Washington Blvd., Southwestern Blvd., Monroe St. / Fulton Ave., North Ave., Belair Rd., Belair Bypass, Conowingo Rd. 81.00 mi. in Maryland; from DC line near Bladensburg north to PA line near Rising Sun Marked north-south. NHS: North of I-695 to PA line. The original road from Baltimore to Washington. Changes have occurred in bypassing Elkridge, where Old Washington Blvd. was MD 477, but decommissioned in the late 1980s. There was also change of course near the Baltimore Beltway (I-695). Little sliver of Old Washington Blvd. near Lansdowne Rd. in Baltimore County is unsigned MD 993, formerly 993B. Paved circa 1914, made part of US 1 with original numbering in 1926. Belair Rd., running straight out from Baltimore to the northeast for more than 10 miles, has had no change in alignment, thus Belair Rd. is one of the few arterial highways in Maryland not to have a companion 'old' road (sometimes numbered itself-see 993 above) darting in and out of view every few miles. It has remained somewhat unscathed because most traffic now takes either I-95 or US 40 in this corridor, and US 1 Belair Rd was the first road in Maryland to have three lanes; one lane in each direction with a "suicide lane" in the middle to accomodate left turn traffic. It has been widened between I-695 and Gunpowder Falls to six lanes in s ome places, to accomodate the busy Perry Hall area. Town of Bel Air bypassed in early 1960s, rest of Belair Rd. became Business US 1. Bypass was extended north around Hickory, opening in 2000. Mile markers along the bypass are in tenths, and seem to be distance north from the Baltimore/Harford county line. Route 1 north of Bel Air crosses the Susquehanna by way of Conowingo Dam., as it passes onward to Philadelphia.

ALT Prince George's Hyattsville Bladensburg Cottage City	US 1 Alternate · Bladensburg Rd, Baltimore Ave 2.09 mi.; from DC line in Cottage City north to US 1 in Hyattsville. Marked north-south.
