Biloxi sits on a peninsula between the Mississippi Sound and the Back Bay, and its roads follow the water. US 90 runs along the beach as a wide boulevard past the lighthouse and the casino strip, crossing the Biloxi Bay Bridge to Ocean Springs on the east. I-10 crosses the northern part of the city, connecting it with Gulfport and New Orleans to the west and Mobile to the east. I-110 links I-10 to US 90 near downtown, crossing the Back Bay on a high bridge. Pass Road runs parallel to the beach through the middle of the peninsula, Popps Ferry Road crosses the Back Bay on the west side, and MS 67 heads north toward Woolmarket and Saucier.
I-110 and US 90 near the casinos are the main slow spots, especially on weekend evenings and during events. The Back Bay bridges are choke points, and breakdowns on them are hard to work around. On the peninsula, streets are narrow in East Biloxi and wider in the newer parts of West Biloxi, while North Biloxi across the bay has the space of a suburban area, with subdivisions and big lots.
Keesler Air Force Base sits in the middle of the peninsula, and many airmen and their families live in and around Biloxi; base access requires the right credentials. Gulfport-Biloxi International Airport is a short drive west. Casino workers often work shifts around the clock, so a repair at home or in the employee lot between shifts is common.
Weekend crowds and events at the casinos bring heavy traffic, and summer storms can close parts of US 90 with flooding or blowing sand. For on-site repairs, weekday mornings and early afternoons are usually the easiest time to reach the beachfront and the peninsula, while North Biloxi and Woolmarket are simple to get to at almost any hour.
