Navigating the Grand Strand requires understanding how major inland arteries feed into coastal corridors like U.S. 17 and S.C. 31. If you're driving into the Myrtle Beach area, relying on default GPS settings often routes drivers directly into heavy congestion on Kings Highway during peak hours. Knowing which bypasses, connectors, and alternate highways to take saves hours of frustration.
The Grand Strand spans roughly 60 miles of coastline from Little River down to Georgetown. Because no direct interstate cuts straight to the oceanfront, drivers must transition from major highways like I-95, I-20, or I-77 onto state-maintained freeways. This guide breaks down the best routes, local bypass strategies, and practical navigation rules for the South Carolina coast.
Core Highway Routes Into the Grand Strand
Getting to the coast efficiently depends on your point of origin. Traffic bottlenecks near Conway on U.S. 501 frustrate many first-time visitors who don't utilize modern multi-lane alternatives.
Coming from the North via I-95
Drivers heading south on I-95 typically exit toward Florence or Dillon.
- From Florence, take U.S. 501 South directly toward Conway and Myrtle Beach.
- Alternatively, exit I-95 at Dillon onto S.C. 9 East, which bypasses the heavy U.S. 501 congestion entirely and feeds straight into the northern Grand Strand near Little River and Cherry Grove.
Coming from the West via I-20 or I-40
If you're traveling across Columbia or Wilmington, your primary objective is connecting cleanly to coastal routes.
- From Columbia, take I-20 east to I-95, then drop down to S.C. 22 (Veterans Highway). S.C. 22 is an interstate-style, multi-lane freeway that bypasses local stoplights and drops you straight onto U.S. 17 near the North Myrtle Beach area.
- From the Wilmington area, use U.S. 74 East to connect to S.C. 9, providing a smooth entry to the northern beaches.
Mastering Local Corridors and Bypasses
Once you arrive on the Grand Strand, local road names dictate your daily travel. Traffic flow changes drastically depending on whether you choose coastal surface streets or high-speed bypasses.
U.S. 17 Business vs. U.S. 17 Bypass
U.S. 17 splits into two distinct paths through the heart of Myrtle Beach. U.S. 17 Business (historically known as Kings Highway) runs right past older motels, restaurants, and shops, featuring dozens of traffic lights. It's ideal if your destination sits right on the oceanfront, but terrible for through-traffic. U.S. 17 Bypass skips some downtown congestion, though heavy commercial development over the years means it still experiences rush-hour slowdowns.
Carolina Bays Parkway (S.C. 31)
For moving quickly up and down the coast, S.C. 31 functions as a primary high-speed artery. With a 65-mph speed limit, it stretches from S.C. 9 in Little River down to S.C. 544 in Socastee. Using S.C. 31 allows you to bypass local stoplights entirely when commuting between the North Strand and South Strand.
Robert M. Grissom Parkway
This route runs parallel to the coast between the Myrtle Beach International Airport and 48th Avenue North, crossing over the Intracoastal Waterway. It's a reliable alternative for local trips within city limits when Kings Highway bogs down.
Common Navigation Mistakes to Avoid
Drivers unfamiliar with the layout often make predictable errors that turn a simple ten-minute drive into an hour-long ordeal.
- Trusting blind GPS during peak check-in days: Saturday afternoons see massive turnover at area resorts. Standard mapping apps often route cars down surface streets where left turns across heavy traffic create gridlock. Check live traffic layers before leaving your hotel.
- Ignoring alternative bridges: Crossing the Intracoastal Waterway happens via a few major bridges (U.S. 501, S.C. 544, S.C. 22). If an accident blocks one bridge, traffic instantly backs up. Memorize alternate inland crossings.
- Underestimating seasonal event traffic: Car shows, sports tournaments at local complexes, and festival weekends alter typical traffic patterns. Give yourself an extra 30 minutes of travel buffer during major event weeks.
Frequently Asked Questions
Which highway is best for avoiding Myrtle Beach traffic?
S.C. 31 (Carolina Bays Parkway) and S.C. 22 (Veterans Highway) offer high-speed, multi-lane alternatives that bypass local stoplights and congested commercial strips.
How do I get to North Myrtle Beach without taking U.S. 501?
Take S.C. 9 East directly from I-95 near Dillon, or use S.C. 22 after crossing the inner coastal regions. Both routes route traffic cleanly to the northern side of the Grand Strand.
Is Kings Highway the same as U.S. 17?
Yes, U.S. 17 Business through Myrtle Beach is historically known as Kings Highway. It features numerous stoplights and heavy pedestrian crossings, making it slow during summer months.
What is the speed limit on S.C. 31?
The speed limit on the Carolina Bays Parkway (S.C. 31) is 65 mph, making it the fastest route for longitudinal travel across the area.
