SR 15A begins at the intersection of
US 17/92 (
SR 15/
600; South Woodland Boulevard) as a western continuation of East Taylor Road, which from there runs east to CR 4101. It forms a western truck bypass for the aforementioned routes around
DeLand, and begins to curve to the northwest just before the intersection with South Adelle Avenue while West Taylor Road resumes in a realigned road just south of the intersection with SR 15A and South Adelle, which returns to the original trajectory that SR 15A replaced. North of the intersection with West Beresford Avenue it becomes part of South Spring Garden Boulevard. Along the way, the otherwise minor intersection with Camphor Lane leads to the NRHP-listed
John B. Stetson House. The sole intersection with a state route along this road, other than those at the termini is
Florida State Road 44 (West New York Avenue), and South Spring Garden Boulevard becomes North Spring Garden Boulevard. Additionally, SR 15A becomes not only a truck bypass for US 17 and 92, but for SR 44 north of this point. Along the way, North Spring Garden Boulevard encounters a grade crossing with
CSX DeLand Spur, and former industrial areas can be found in the vicinity of the crossing between Wisconsin and Minnesota Avenues, primarily along the east side. North of Plymouth Avenue, the road changes from a four-lane undivided highway to a four-lane divided one. The truck bypasses for US 92 and SR 44 along SR 15A end at the intersection of Volusia County Road 92 (
International Speedway Boulevard), across the street from Grantham Way, the latter of which is the entrance to the Glenwood Springs residential community. VCR 92 connects to motorists and truck drivers the northern end of the US 17/92 overlap. North of that intersection, SR 15A leaves the city limits and runs through semi-rural surroundings in unincorporated segments of Volusia County. The only signalized intersection in this vicinity is with Glenwood Road (
Volusia County Road 4088), an unmarked west to east county road that leaves its
community namesake immediately west of the intersection with SR 15A, and has an eastern terminus at the fork in the road with US 17 and
SR 11. The last intersection before the route's northern terminus is two streets obstructed by the divider; Tall Oaks Road leading from the southbound lanes and Williamsbridge Road leading from the northbound lanes. After this SR 15A curves to the northeast and terminates at
US 17/FL 15 (North Woodland Boulevard), north of DeLand. It continues northeast from its northern end as
CR 15A to
SR 11. ==Major intersections==
