Answer
Coastal Highway (MD 528 / DE 1) runs continuously north from uptown Ocean City through Fenwick Island into Delaware beach towns without mountain passes. Summer Saturday afternoons can turn a short map distance into an hour-plus crawl. Leave before 10 a.m. or after evening dinner rush when possible.
