COMMUNITY WELL-BEING

Though the Martin Marietta/Shaw partnership is still relatively new, the Company is confident there will be ample
opportunities for the company and the university’s students to work together. “Partnering with Shaw University – a
renowned institution right here in our corporate home of Raleigh – is directly aligned with our commitment to investing in
the strength of the communities in which we live and work,” Santre said.

Founded in 1865, Shaw University is a private liberal arts institution affiliated with the Baptist Church. It was the first
historically Black university in the Southern United States and is among the oldest such universities in the country.
Throughout its history, the school has consistently moved academics forward in North Carolina. Shaw was the first college
in the state to offer a four-year medical school, the first institution of higher learning established for freedmen after the
Civil War, and the first historically Black university to open its doors to women. Learn more at shawu.edu.

Historic Colorado Quarry Bridge Finds a New Home

100-year-old Structure Once Used by Horses Then Customer Trucks Will Now Serve Park Community
The Colorado bridge that has long connected Parkdale Quarry to the world outside is shrouded in 100 years of
speculation and hearsay. Now, as site leadership moves to make necessary upgrades to the quarry grounds, the Company
moved to preserve to the bridge. “We have absolutely no architectural or engineered drawings of this bridge, but what
we do know is that it was built by a German immigrant sometime between 1915 and the mid-1920s,” Mike Sheahan,
Business Unit Consultant said. “At the time, it served the Harvey Ranch, which owned most of the land between the
Arkansas River and the Bureau of Land Management holdings to the north and west.”

What the bridge’s day-to-day life looked like for much of its first 70 years isn’t entirely clear, however since the 1990s, it
has served a variety of quarry owners. But the bridge was originally intended for horses and covered wagons, not haul
trucks and mining equipment. “It’s about 13 feet wide, which really limited what we were able to bring across it,”
Sheahan said. “Much of the equipment we use here is 12- to 13-feet wide, so it has always been difficult just to find
truckers comfortable and skilled enough to get things across.”
