There is no interchange with I-85. However, there are ramps to southbound Buford Highway from southbound Piedmont Road as well as a ramp from northbound Buford Highway to northbound Piedmont Road; there is no access to I-85.
North of I-85, the road crosses over a CSX Transportation rail line. It heads north and northwest to SR 141 (Peachtree Road SW). The highway heads northwest to meet its northern terminus, an intersection with US 19/SR 9 (Roswell Road) in North Buckhead. SR 237 is known as Piedmont Road NE for its entire length.[1]
No section of SR 237 is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility and defense.[4]
History
SR 237 was established at the latest by 1946 along an alignment that started at US 23, which traveled on Cheshire Bridge Road and a southern continuation of Piedmont Road NE at that time. This is just south of the current southern terminus. SR 237 headed north along Piedmont Road NE as it does today.[2][3] In 1967, US 23 was moved farther to the east. However, it is not clear whether the portion of SR 237 between the former US 23 segment and its current southern terminus was decommissioned at this time.[5][6]
