In the mid-1950s, the section of MD 32 from Westminster west to Emmitsburg was renumbered as an extension of MD 97. MD 32 would later be restored to its old route through Westminster and west toward Taneytown when MD 97, which is now MD 140 west of Westminster, was relocated in the early 1960s. MD 32 was truncated to Westminster in the late 1970s and rolled back to its present northern terminus in 2001. Along its present course, MD 32 bypassed Sykesville and was relocated from Clarksville to Glenelg in the early 1960s.

History


Original construction

When the Maryland State Roads Commission (MDSRC), the predecessor of MDSHA, laid out its original state road system in 1909, the commission included the roads from Westminster to Taneytown and from West Friendship to Westminster via Eldersburg. These highways already contained several stretches of improved highway; Main Street in Westminster and the highways for on either side of Gamber and for on either side of Sykesville were paved by 1910. In addition, the designated state roads included two turnpikes: the Westminster and Meadow Branch Turnpike operated from the western city limit of Westminster northwest to Fountain Valley on the road to Taneytown; and the Westminster and Fenby Turnpike operated from the southern city limit of Westminster to Fenby. In 1911, the whole highway from West Friendship to Eldersburg was completed after the addition of wide

sections on either side of the existing paved road through Sykesville. That same year, construction began on the state road between Eldersburg and Fenby. The roads from Eldersburg to the existing paved road through Gamber and from Gamber to Fenby were completed with a wide macadam surface in 1912 and 1913, respectively. The road from Fountain Valley to Taneytown was paved as a wide concrete road from Fountain Valley through Frizzelburg in 1914 and from there to Taneytown in 1915. The former turnpikes still remained to be improved in 1915; those roads were resurfaced with macadam by 1919 to complete the original state road from West Friendship to Taneytown. The next portion of what was to become MD 32 to be constructed was an extension of the Taneytown road northwest through Emmitsburg, which was planned by 1915. The sections from Taneytown to the

and from the river west toward Emmitsburg were completed as a wide concrete road by 1919. The remaining to Emmitsburg were underway by 1920 and built as a wide concrete road by 1921. The highway was completed from Emmitsburg northwest to the Pennsylvania state line by 1923. When MDSRC started assigning numbers to its state roads in 1927, the highway from US 40 in West Friendship to the Pennsylvania state line northwest of Emmitsburg was designated MD 32. The portion of MD 32 from Glenelg to Savage was originally designated MD 106. This highway was paved in concrete from Dayton to Clarksville and from Clarksville to about west of the Middle Patuxent River near Simpsonville by 1923. That same year, a concrete road was added south from West Friendship to the Middle Patuxent River. The concrete road from Clarksville was extended to the Middle Patuxent River opposite Simpsonville in 1925. A macadam road was built from Atholton to Oakland Mills Road in

between 1924 and 1926. Guilford was connected to US 1 near Savage with a gravel road by 1927. The gap in MD 106 through Simpsonville was filled with a concrete road in 1929 and 1930. MD 32 was extended southwest from the Middle Patuxent River to north of Glenelg around 1933. MD 106 was extended north from Dayton to Glenelg as a macadam road in 1934. The gap in the highway north of Glenelg was filled by 1946, by which time MD 32 had been extended south and east over the course of MD 106 to Savage.


Improvements

The first major improvement to the original course of MD 32 was the replacement of the highway's one-lane
covered bridge A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered woo ...
over the Monocacy River with a wider triple-span concrete arch bridge in 1925. The highway was widened to from Westminster to just east of Taneytown by 1930 and from Taneytown to the Pennsylvania state line by 1934. MD 32 was reconstructed and widened again from Emmitsburg to the Pennsylvania state line in 1948 and through Taneytown in 1949. When US 40 was relocated as a four-lane divided highway through West Friendship in 1951, the new highway was placed on a bridge over MD 32 and a two-way ramp added to connect the grade-separated highways. MD 32 was relocated between Eldersburg and Louisville and a new bridge was constructed over Morgan Run in 1952 to replace the old road that would have been submerged by the filling of Liberty Reservoir. In 1956, the portion of MD 32 from Fenby north to Westminster and from Westminster west through Taneytown and Emmitsburg to the Pennsylvania state line was renumbered MD 97, which had been extended north from Howard County. The portion of MD 32 from MD 26 in Eldersburg to MD 97 in Fenby was transferred to county maintenance at the same time. In 1960, the road from Eldersburg to Fenby returned to the state highway system. In addition, MD 97 was moved to a new alignment, New Washington Road; the new alignment ran from Fenby to US 140, which then connected Baltimore with Gettysburg, in Westminster. MD 97 then followed the Westminster Bypass to the northwest side of the city. Subsequently, MD 32 was extended along its original alignment through Westminster to MD 97 near Western Maryland College (now

). MD 32 would later be assigned to its original alignment from Fountain Valley to east of Taneytown when MD 97's new alignment between the two communities was completed in 1965. The disjoint segment of MD 32 was renumbered MD 832 in 1978. In 1979, US 140 was decommissioned; the highways from Baltimore to Westminster and from Westminster through Emmitsburg became MD 140. MD 97 was moved to its present course from Westminster toward Gettysburg. MD 32's northern terminus was rolled back to MD 31 around 1987. The state highway was truncated at the Westminster city limit in 2001 following the reconstruction of Main Street and its transfer to city maintenance. MD 32 was reconstructed and widened from Sykesville to Eldersburg starting in 1957 and from West Friendship to just south of Sykesville in 1958. The state highway's bypass of Sykesville was completed in 1963; the old road through the center of Sykesville became MD 851. MD 32's new bridge across the Patapsco River was the longest of only three aluminum triangular box beam girder bridges constructed in the United States. The girder system was topped by a concrete slab deck and underlain with standard concrete abutments and piers and steel bearing pads on which the aluminum girders rested. These bridges, which were designed by Fairchild Engine and Airplane Company, were constructed of aluminum due to that metal's light weight but similar strength compared to steel. Many experimental aluminum bridges were built due to a severe shortage of steel in the early 1960s. Aluminum bridges are rarely constructed because they are much more expensive than steel and concrete bridges. In the 1990s, MDSHA discovered the bridge's rarity while conducting a bridge inventory. The inventory also found premature deterioration of its supports due to

involving the steel bearing pads and aluminum girder structure. Because repairing the structure would have been extremely difficult, MDSHA decided to build a replacement bridge immediately to the west of the aluminum bridge; the new bridge opened in 2004 along with a slight relocation in MD 32 on both sides of the bridge. The aluminum bridge was added to the state's Historic Bridge Registry and was left in place as a historic landmark after MD 32's new bridge over the Patapsco River opened.


Patuxent Freeway

In 1956, MD 32 was extended east on Guilford Road from US 1 to the Howard – Anne Arundel county line at Annapolis Junction. The state highway was relocated to its present alignment from Glenelg to Clarksville between 1961 and 1964, bypassing Ten Oaks Road. MD 32 was expanded to a four-lane divided highway in West Friendship when its interchange with I-70 was reconstructed as a diamond interchange in 1973. MD 32 was extended east into Anne Arundel County in 1969 when the designation was extended to just east of the Baltimore–Washington Parkway on the edge of Fort George G. Meade. The first two sections of what would become the Patuxent Freeway opened in 1972. A short section of divided highway opened from just west of Oakland Mills Road in Guilford to a turnaround just west of Vollmerhausen Road that included MD 32's modern interchange with I-95. The other section was a two-lane road from MD 175 in Odenton northeast along Sappington Station Road and then east along the current alignments of MD 32 and I-97 to MD 178 just east of I-97 Exit 5 in Crownsville. The eastern section, which from 1972 to 1977 was one of the three disjoint sections of mainline MD 32 between Crownsville and Taneytown, included an interchange with MD 3 in Millersville. As of 1978, MD 32's interchange with the Baltimore–Washington Parkway was a partial cloverleaf interchange with four ramps on the north side of MD 32—due to the state highway closely paralleling the

's spur to the military base—and a fifth ramp from the northbound Parkway to eastbound MD 32. The MD 3 interchange included the ramps to and from MD 32 in the direction of Fort Meade plus a ramp from westbound MD 32 to northbound MD 3. All other movements were made via MD 178 or Millersville Road. Construction on the Patuxent Freeway resumed in 1981 in Howard County. The freeway opened from Dorsey Run Road to US 29 in 1985. The freeway was extended across the Middle Patuxent River to tie into the existing two-lane road near Cedar Lane by 1987. The new highway was extended east from Dorsey Run Road to just west of the Baltimore–Washington Parkway as a four-lane divided highway that same year. Sections of MD 32's old alignment became part of MD 732. The highway from Dorsey Run Road to the Parkway was upgraded to a freeway with the completion of interchanges at Dorsey Run Road and a ramp to Guilford Road in 1991. The interchange between MD 32 and the Baltimore–Washington Parkway was upgraded to a full cloverleaf around 1993. The final section of the Patuxent Freeway in Howard County opened from west of US 29 to west of MD 108 in 1996. I-97 was under construction from Annapolis to Millersville by 1987. When that section of the Interstate was completed in 1989, the highway took over the portion of MD 32 from MD 178 to MD 3. The easternmost portion of MD 32 became I-97's Exit 5 interchange ramps; the MD 3 interchange was upgraded to provide full access. Also in 1989, construction began on MD 32 between the Baltimore–Washington Parkway and I-97. MD 32 was extended as a four-lane divided highway along the existing road from the parkway east to MD 198 and as a two-lane road on a new alignment from MD 198 to MD 175. The sections of MD 32 from MD 198 to MD 175 west of Odenton and from Burns Crossing Road to I-97 were under construction to expand them to a freeway; the freeway segment from MD 175 to Burns Crossing Road on the north side of Odenton was also under construction. The freeway between MD 198 and MD 175 was complete by 1991. The remainder of the Patuxent Freeway from Fort Meade to Millersville was completed in 1993. In 2000, construction began on the gap in the Patuxent Freeway through Fort George G. Meade. MD 32's interchanges with MD 198 and Samford Road were completed in 2002. The MD 198 project involved extending the latter highway east along the northern edge of Tipton Airport so MD 198 could tie into the fort's Mapes Road entrance; the Mapes Road intersection east of MD 198 was also eliminated by the construction. The Patuxent Freeway through Fort Meade was finished when MD 32's interchange with Canine Road was completed in 2005.


Sykesville Road upgrade

MDSHA has long-term plans to upgrade MD 32 to a four-lane freeway from MD 108 to I-70. The first project, which involved constructing a modified dumbbell interchange to connect MD 32 with Burntwoods Road, Ten Oaks Road, Pfefferkorn Road, and Ivory Road in Glenelg, was completed in 2008. The next project involved the construction of a diamond interchange at Linden Church Road, which, before the dumbbell interchange was completed in the fall of 2013, met MD 32 at a pair of signalized, three-way directional crossover intersections between Glenelg and Clarksville. Several other interchanges will be constructed or modified: *At MDSHA's Dayton Shop south of Glenelg, a half-diamond interchange will be built on the southbound side of MD 32 and a
right-in/right-out Right-in/right-out (RIRO) and left-in/left-out (LILO) refer to a type of three-way road intersection where turning movements of vehicles are restricted. A RIRO permits only right turns and a LILO permits only left turns. "Right-in" and "left-in" r ...
interchange constructed for northbound MD 32 traffic to access the maintenance facility. *North of Glenelg, Rosemary Lane will be extended west to cross over MD 32. The county highway will be connected to MD 32 via right-in/right-out interchanges between the state highway and frontage roads. *In West Friendship, northbound MD 32 would have half of a partial cloverleaf interchange with MD 144. Access between MD 144 and southbound MD 32 would be via a right-in/right-out interchange with a frontage road. MD 144's intersections with the frontage road and the ramps to and from northbound MD 32 will be roundabouts. *MD 32's interchange with I-70 will be transformed from a diamond interchange to a partial cloverleaf interchange with free-flowing ramps from MD 32 to I-70.


Junction list

MD 32 is signed east–west from I-97 in Millersville to MD 108 in Clarksville and north–south from MD 108 to Westminster.


Auxiliary routes

MD 32 has three existing auxiliary routes: *MD 32AA is the designation for Sappington Station Road, which runs from westbound MD 32 west to MD 175 in Odenton. The state highway begins at the westbound MD 32 exit ramp for Exit 3. MD 32AA merges with the entrance ramp to westbound MD 32 and intersects the northern section of Burns Crossing Road before crossing over MD 32. The state highway intersects the southern section of Burns Crossing Road and heads southwest to its terminus at a roundabout with MD 175 (Annapolis Road), Odenton Road, and Higgins Drive. *MD 32AH is the designation for Lodigiani Avenue, a spur east from Gambrills Road just south of Gambrills Road's overpass of MD 32 in Gambrills. *MD 32B is the designation for the unnamed connector between MD 32 and MD 851H, which is a spur of old alignment of MD 32 north of West Friendship.
