A towering symbol of the rip-roaring building boom on the Charleston peninsula is about to fade from the city skyline.

A construction crane perched over the 10 WestEdge project near the hospital district will be dismantled starting June 20. The work will require the West Ashley-bound lanes of Spring Street to be closed between Hagood Avenue and Lockwood Boulevard until 6 a.m. on June 23, according to the WestEdge contractor.

The entrance to the Holiday Inn on Spring will remain accessible. Drivers needing to reach Lockwood during the closure will be detoured right onto Hagood and then left onto Fishburne Street.

The tower crane that's coming down is one of two on the WestEdge property near the Ashley River. It's also one of seven that are visible around the peninsula from places such as the Ravenel Bridge.

Many cities refer to their "crane index" as an informal barometer for building activity. The needle began to climb in downtown Charleston several years ago as work got underway on several tall structures in relatively tight areas of the peninsula. On those projects, cranes are necessary to move and deliver heavy materials.

The nine-story 10 WestEdge is one such example. The 850,000-square-foot, mixed-use building will include 350 upscale apartments, a Publix supermarket and an 870-space parking garage. The first phase, which includes the grocery store, is scheduled to be completed in October.

Other dense commercial projects proposed for the upper peninsula are expected to require big cranes as well.
