FLORENCE — An environmental group is urging its supporters to attend a meeting on the proposed construction of Interstate 73.

The Sierra Club considers the highway a boondoggle and is urging its members to attend the forum scheduled for Friday at Francis Marion College. That call brought a quick response from the tourism community on the Grand Strand.

Brad Dean, president and CEO of the Myrtle Beach Area Chamber of Commerce says environmental activists often try to slow economic progress through what he called “fear, manipulation and misinformation.”

The interstate will eventually connect with Michigan, running 90 miles through four South Carolina counties at a cost of $2 billion.

It will provide the first interstate link to Myrtle Beach, the heart of South Carolina’s $14 billion tourism industry.
