Approaching junction Maryland 161 (Main Street) near Darlington along U.S. 1 (Conowingo Road) north. Maryland 161 (Darlington Road) links U.S. 1 with Maryland 155 (Level Road) and Susquehanna State Park in eastern Harford County Photo taken 06/05/05.
Maryland 161 (Main Street) splits with Maryland 623 (Castleton Road) just before meeting U.S. 1 (Conowingo Road). Maryland 623 follows Castleton Road north across U.S. 1 to Berkley. The route provides a more direct connect to U.S. 1 north from Maryland 161. Photo taken 06/05/05.
U.S. 1 (Conowingo Road) north at Maryland 623 (Castleton Road). Maryland 623 continues north from Castleton Road onto Flintville Road to Slate Hill, Pennsylvania. Photo taken 06/05/05.
This U.S. 1 reassurance shield is located along northbound as the highway approaches a weigh station after the intersection with Maryland 623. Photo taken 04/30/04.
This mileage sign along northbound U.S. 1 provides the mileage to Rising Sun (10 miles) and Oxford (13 miles) just prior to reaching Conowingo Dam. The Conowingo Dam holds back a reservoir along the Susquehanna River and is part of a larger flood control system on the river. Photo taken 04/30/04.
U.S. 1 makes an abrupt curve ahead of the Conowingo Dam crossing of the Susquehanna River. A wayside park lies along the west banks of the river adjacent to the curve. Photo taken 06/05/05.
U.S. 1 northbound reaches Conowingo Dam, which spans the Susquehanna River southwest of the town of Conowingo. Conowingo Dam is a fully functioning power generating facility, opened in 1928 and expanded in 1978. A concrete dam, it is 105 feet tall and is jointly owned by Susquehanna Power Company and Philadelphia Electric Power Company (PECO). Photos taken 04/30/04 & 06/05/05.
U.S. 1 narrows considerably across Conowingo Dam; midway across the Susquehanna River is the dividing line between Harford and Cecil Counties. Conowingo Dam represents the only toll-free road crossing of the Susquehanna within Maryland. Photos taken 06/05/05.
Maryland 222 reaches its northern terminus at its intersection with U.S. 1. Formerly U.S. 222, Maryland 222 represents a truncated section of U.S. 222 from Conowingo southeast to U.S. 40 at Perryville. The route is to narrow for trucks, and the U.S. 222 designation was likely retracted because it is not an exceptional through route to Interstate 95. Photo taken 06/05/05.
Maryland 222 is the former alignment of U.S. 222 from U.S. 1 in Conowingo southeast to U.S. 40 at Perryville. In 1995, U.S. 222 was removed from this stretch in an effort to reduce traffic on a fairly narrow and winding road with a low clearance railroad bridge at Port Deposit. The truck route was placed in a previous effort to bypass large truck traffic from Port Deposit for the drive between Conowingo and Perryville. The truck alternate route of Maryland 222 is available via U.S. 1 north, Maryland 276 south, and Maryland 275 south before meeting Maryland 222 just north of Interstate 95. The new southern terminus of U.S. 222 is located just ahead on U.S. 1. Photo taken 04/30/04.
U.S. 1 and former U.S. 222 north travel along Conowingo Road into the village of Conowingo at junction U.S. 222 (Rock Springs Road) at Rowlandsville Road. Overall U.S. 222 links Cecil County with Lancaster, Pennsylvania in conjunction with Pennsylvania 272. Photo taken 06/05/05.
U.S. 222 begins its northerly journey via Rock Springs Road from U.S. 1 at Kilby Corner. The federal route travels to Lancaster, Reading, Kutztown and the Allentown metropolitan area in Pennsylvania. This intersection marks the southern terminus of U.S. 222, which has a fraction more than three miles for its entire length in Maryland. Photos taken 04/30/04 & 08/11/05.
A truck alternate route for Maryland 222 south is signed along northbound U.S. 1 (Conowingo Road) after the U.S. 222 (Rock Springs Road) intersection. Maryland 222 Truck is a remnant of U.S. 222 Truck. The alternate route is mandatory for large trucks due to the narrow nature of Maryland 222 (Main Street) in Port Deposit. Photo taken 04/30/04.
Between U.S. 222 and Maryland 273, U.S. 1 passes by an old alignment along Porters Bridge Road. Porters Bridge Road is designated as Maryland 591, but it is not signed as such from the mainline. The bridge itself, which crossed the Octoraro Creek, was decommissioned and later removed, thus rendering Maryland 591 into a split route on either side of the old bridge. Photo taken 08/11/05.
The U.S. 1 Octoraro Creek bridge itself is an older span with a concrete guardrail. Photo taken 06/05/05.
U.S. 1 approaches Maryland 273, which follows Rising Sun Road east through Rising Sun, Calvert, Fair Hill, and Appleton, then changes into Delaware 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, Maryland 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. Photo taken 07/25/04.
U.S. 1 and Maryland 273 split here, with U.S. 1 continuing north toward Nottingham and Oxford in Pennsylvania. Upon crossing the state line and continuing northeast to Kennett Square (Junction Pennsylvania 82), U.S. 1 is a freeway, and it remains that way until reaching the Philadelphia metropolitan area. Maryland State Highway Administration advises motorists headed to Interstate 95 not to use Maryland 273 and instead follow Truck Maryland 222/Maryland 276 south. Photo taken 07/25/04. Photos taken 06/05/05 & 07/25/04.
U.S. 1 reassurance marker posted beyond the westbound Maryland 273 connector road to the federal highway. Photo taken 08/11/05.
Shortly after the Maryland 273 split is the turn off for South Truck Maryland 222 and Maryland 276 (Jacob Tome Memorial Highway) to Interstate 95. This is not the most direct route but is the preferred route for trucks. Do not continue straight ahead on U.S. 1 in search of Interstate 95; they do not rejoin until north of Philadelphia! Photo taken 04/30/04.
As noted previously, Truck Maryland 222 south departs U.S. 1 and follows Maryland 276 (Jacob Tome Memorial Highway) south to Maryland 275 south back to Maryland 222. Maryland 276 bypasses the nearby town of Rising Sun to the west. Photo taken 04/30/04.
A set of flashers governs the northern terminus intersection of Maryland 276 with U.S. 1 (Conowingo Road). Slicers Mill Road stems north from the junction into rural farm land. Use Maryland 276 south for Rising Sun by way of West Pearl Street and Maryland 273 (West Main Street). Photo taken 07/25/04.
U.S. 1 northbound on Conowingo Road after its intersection with Maryland 276 (Jacob Tome Memorial Highway). The federal route originally traveled through Rising Sun via Rising Sun Road / Main Street (Maryland 273) and Walnut Street. The highway stays well north of the town now and intersects Walnut Street in one mile. Photo taken 07/25/04.
