Turnpike, the Bel Air
Turnpike of Harford County, and Conowingo Bridge from their private operators. The SRC also paved its first section of the road from Oakwood to the crossing of Octoraro Creek that year. The road from Rising Sun to Sylmar Road was completed in 1911, along with Bel Air Road from the Baltimore city limits to Franklin Avenue. The paved section along Bel Air Road was extended northeast to Hamilton Avenue in 1912. That year also saw the first paving in Harford County from Kalmia to Deer Creek. The remainder of the highway in Harford County—from Little Gunpowder Falls to Bel Air and from Deer Creek to the Conowingo Bridge—was completed in 1913. Bel Air Road was finished in Baltimore County in 1914 and was paved from North Avenue to the Baltimore city limits, then just north of Erdman Avenue, in 1915. The highway was paved between the Conowingo Bridge and Oakwood in 1914. The state road was constructed along the alignment of the turnpikes without digression except for a relocation at Gunpowder Falls to reduce the grades on the hills. The final sections of what was to become US 1 were paved in Cecil County between 1917 and 1921, when the gap between Octoraro Creek and Rising Sun was filled and the Sylmar Road link from east of Rising Sun to the Pennsylvania state line was paved.

US 1-designated length by 1957. By 1960, this bypass had become the northbound lanes of the present one-way pair. US 1 north of
Baltimore was reconstructed to modify curves and widen the road in the 1950s. The highway was reconstructed in Cecil County from Conowingo Dam to Rising Sun in 1952 and 1953 and from Rising Sun to Sylmar in 1954. US 1 in Harford County was reconstructed from Little Gunpowder Falls to north of Deer Creek in 1952 and 1953 and to Conowingo Dam between 1954 and 1956. In Howard County, the highway was resurfaced from Elkridge to Waterloo in 1954 and from Waterloo to the Patuxent River in 1956. By 1958, US 1 was being widened from Laurel to Beltsville. The highway's bypass of Rising Sun was completed in 1957. MD 273 was extended west from Sylmar through Rising Sun along the old alignment to the southern end of the bypass. The Bel Air bypass was placed under construction in 1964 and completed in 1965, resulting in the designation of US 1 Bus. along the old road through Bel Air. The Bel Air bypass was extended north around Hickory in 2000, with US 1 Bus. extended to meet the northern end of the bypass.

By 1915, State Route No. 1 was completely paved with the addition of the highway on a new alignment between Beltsville and Contee, the filling of the gaps in College Park and Hyattsville, and construction between Elkridge and Halethorpe. The road was constructed a minimum of 14 feet (4.3 m) in width with macadam, gravel, and concrete, with curves straightened and grades reduced. Concrete sections in Laurel, College Park, and Bladensburg were among the first concrete roads in Maryland when they were poured in 1912. Concrete girder bridges were built at Northeast Branch and the Anacostia River in Bladensburg. A concrete bridge was built over the Patapsco River at Elkridge to replace an earlier iron bridge. Due to heavy traffic and inadequate initial construction, many of the sections constructed in the first few years of state aid had to be later rebuilt.

Feeling the work done by the counties with state funds was inadequate, in 1906, the general assembly further appropriated a total of $ 90,000 (equivalent to $ 22.9 million in 2023)—$ 30,000 each in 1906, 1907, and 1908 (equivalent to $ 7.63 million, $ 7.16 million, and $ 7.18 million in 2023)—toward reconstruction of the
Baltimore–Washington Boulevard. The 30-mile (48 km) road between the city limits of Washington DC and Baltimore was officially designated State Route No. 1. Another $ 174,000 (equivalent to $ 4.16 million in 2023) was appropriated by the state legislature in 1908. The 1908 act contained stipulations requiring a realignment of the road between Beltsville and Contee to eliminate two grade crossings of the
1533:, US 1 was relocated from Baltimore Avenue and Bladensburg Road between Washington DC and Hyattsville to Rhode Island Avenue, which was widened to 36 feet (11 m) in 1940. Rhode Island Avenue between Mount Rainier and Hyattsville had originally been MD 411. The old US 1 south of Hyattsville became US 1 Alt. Despite these relocations and upgrades, true relief did not come until the first limited-access highway between Baltimore and Washington DC, the B–W Parkway, was completed in 1954 to remove long-distance traffic from US 1. With the completion of that highway and later the Baltimore Harbor Tunnel Thruway (I-895) in 1957 and, later, I-95, US 1 between the two cities became a highway mainly for local traffic.

of "hot dog highway". The captive audience also led to the construction of over 1000 billboards between the two cities, spurring another nickname: "billboard boulevard". US 1 was also nicknamed "bloody Mary" due to the very high accident rate on the highway. After 1930, businesses were packed up to the edge of the four-lane, shoulder-less road that was largely built on an alignment poorly suited for the increasing speeds of vehicles. Thus, further expansion of the highway or safety improvements were impossible without expensive condemnation proceedings or relocating the highway. Businesses were adamantly against the latter solution.

removal of streetcar tracks and expansion to a divided boulevard on
Wilkens Avenue, to handle the increased traffic as a "through-street". By 1946, a US 1 bypass was signed following Caton Avenue north from Wilkens Avenue, continuing on Hilton Street to North Avenue, then taking North Avenue east to rejoin US 1 at Monroe Street. Southwestern Boulevard was completed in 1950 as a dual highway through Arbutus, with grade separations with Sulphur Spring Road and Francis Avenue. US 1 was moved to its present alignment along that boulevard and Wilkens Avenue and old US 1 through Halethorpe was designated US 1 Alt.
1438:, as well as the severe winter of 1917–1918, devastated the highway. As a result, in 1918 and 1919, the highway was reconstructed from end to end. Some sections of the highway were completely rebuilt with concrete, while, along 18 miles (29 km) of the road, concrete shoulders, among the first applied in Maryland, were added to both widen and strengthen the road. By 1919, the entire length of the Baltimore–Washington Boulevard was a minimum width of 20 feet (6.1 m). The only significant realignment during this reconstruction was the straightening out of Dead Man's Curve 0.5 miles (0.80 km) south of Elkridge.

The Washington and Baltimore Turnpike had its chartered revoked in 1865 and the highway was turned over to the supervision of the counties. The toll bridge at Elkridge was sold to the counties in 1869.
