CHARLESTON COUNTY, SC (WCSC) - A pair of Charleston County bridges rated as structurally deficient will be replaced in a two-phase project.
Lane closures began Monday for the O'Hear Avenue Bridge over Noisette Creek, according to District Construction/Maintenance Engineer Kevin Turner.
That bridge's replacement is expected to be in place by May 12, 2015, and crews will then move to the Spruill Avenue Bridge, whose replacement should be completed by January 17, 2016, barring unforeseen delays, officials say.
The first half of the project will require a detour away from the O'Hear Avenue Bridge via Bexley Street and Spruill Avenue. The detour totals 2.3 miles, the SCDOT says.
Traffic on Spruill Avenue will be detoured along East Montague Avenue, Rivers Avenue and McMillan Avenue, for a total of 5.3 miles, during the second phase of the project.
A bridge rated as "structurally deficient" is considered being in relatively poor physical condition and/or inadequate to handle truck weight.
The rating made the bridges eligible for Federal Bridge Replacement funding, officials say.
