This week's industry milestone: The first cable-stayed bridge with a concrete superstructure to be built in the U.S. was the Pasco-Kennewick Intercity bridge crossing the Columbia River in Washington State, which opened to traffic in 1978. The main spans were 407 ft (124 m), 981 ft (299 m), and 407 ft (124 m).

Shelby Materials - This ready mixed concrete producer has been a family-owned company for 50 years. Its heritage stems from various companies founded and acquired by the Haehl and Wheeler families dating back to the mid 1940s. John D. Haehl, Sr., and Thomas J. Wheeler started in the crushed stone business in 1946 when they founded the Cave Stone Company in Norristown, IN. In 1951, Haehl and Wheeler were part of a group that purchased Barker Sand and Gravel, Inc. in Shelbyville, IN. After the purchase, the two opened a ready mixed concrete plant on the property and renamed the company Shelby Gravel, Inc. Read more.
