Yes, there is indeed a tunnel under Ocean Boulevard, specifically in Myrtle Beach, South Carolina. This tunnel runs beneath Ocean Boulevard by the Sea Mist Oceanfront Resort and is known as the only underground tunnel in Myrtle Beach. It features a unique mural and is located near a public beach access. However, as of summer 2023, this tunnel is no longer maintained. Additionally, the phrase "Did You Know That There's a Tunnel Under Ocean Blvd" is also the title of a song by Lana Del Rey, inspired by a sealed tunnel under the Jergins Trust Building on Ocean Boulevard in Long Beach, California. This tunnel has mosaic ceilings that are well preserved but sealed off from public access. The song brought renewed interest to that tunnel, which is planned to reopen as a speakeasy connected to a new Hard Rock Hotel by 2027. So, there are notable tunnels under different Ocean Boulevards—one in Myrtle Beach related to the resort and another historically significant one in Long Beach, California, connected to Lana Del Rey's song.
