Interstate Interchange

Greenville, SC – This $231 million project is designed to improve safety and increase efficiency in traffic flow for Upstate SC. Construction began in early 2016 to create a new interchange, which will include widening of roads, road improvements and construction of ten new bridge structures.

Due to the nature of the project, it requires 24/7 oversight. BLE was engaged to provide construction engineering and inspection services for SCDOT, with 5 inspectors on site. BLE’s construction materials inspections have included foundation and backfill construction inspection of the mechanically stabilized earth (MSE) walls, storm drain pipe installation and backfill inspection, and inspection of the concrete for foundations and barrier walls. BLE also tested the roadway embankment soil for stability.
