Worldwide industrial services giant Harsco Corp. last week said it secured a three-year $20 million extension to its scaffolding services contract to support the final phase in the repainting of the Forth Rail Bridge in Scotland.

The contract extension from Balfour Beatty continues a multi-year program during which Harsco has been engineering and installing complex scaffolding structures and work platforms that give work crews access through the bridge, without disrupting the 200 trains that cross the bridge daily. The bridge runs 1.5 miles in length and is the oldest cantilever bridge in the world, opened in 1890.

Harsco Corp. is based in Harrisburg, Pa.
