Mississippi Highway 603 (MS 603) is a 25.0-mile-long (40.2 km) state highway in Hancock County, Mississippi. The highway generally runs north–south from its southern terminus at U.S. Route 90 (US 90) in Waveland through Bay St. Louis and Kiln to its northern terminus at MS 53 near Necaise. The road is maintained by the Mississippi Department of Transportation (MDOT). MDOT and Mississippi's law code define MS 603's southern terminus as its intersection with MS 43 in Kiln.^[2]^[3] However, many maps such as Google Maps and MapQuest, and local signage show the highway continuing farther south to Waveland.^[4]'^[5] The road that became MS 603 has existed since 1927, and the highway was designated in 1950. The highway was also partially paved, from Waveland to Kiln, in 1950 and was completely paved in 1957. An interchange was created at Interstate 10 (I-10) in 1960.^[6]
