[4] The town of Concrete has undergone several incarnations, the earliest being a settlement at the northwestern junction of the Baker and Skagit Rivers, known as "Minnehaha."

After the Superior Portland Cement Company plant was built in Baker in 1908, it was decided to merge the two towns.

[6] Built in 1916–1918 and so named for the Scottish immigrant, local settler, and Skagit County Commissioner who promoted its construction.

[7] At the time, its graceful arch was the longest single-span reinforced concrete bridge in the world[8] or perhaps just in the West[7] and has been listed on the Washington State and National Historic Register since 1976.

[9] Until 1972, when the Washington State Department of Transportation re-routed Highway 20 (then known as Star Route 20) outside the town, the Thompson Bridge was the only connecting thoroughfare across the Baker River and into eastern Skagit County.

The bridge was originally designed by Bowerman and McCloy Consulting Engineers and built by J.R. Wood Contractors (both of Seattle).

Constructed with the typical and necessary scholastic appointments and one visible and unusual difference: the central portion of the building was built over the road leading to it.

CHS's sports teams participate in the Northwest 1B/2B league under the Washington Interscholastic Activities Association.

Concrete's Future Business Leaders of America was the fastest growing in the state during the 2012-13 school year.

When Robert and June Fader purchased the newspaper upon Dwelley's retirement in late 1970, the building remained the home for the weekly.

When the building was no longer used as a schoolhouse, it was moved to its present location on West Main Street, next to the current post office.

In its present location, the building has served alternately as a library, senior-citizen center, the city's current town hall with a satellite office for the Skagit County Sheriff's Department.

Originally built in 1923, the stage of the Concrete Theatre has entertained audiences with vaudeville, boxing matches, silent films and later what were known as "the talkies".

Originally the Monrad Grocery built in 1915, the expanded space now features an ice cream parlor, as well as the theatre box office and an additional meeting/screening room.

In 1993, the novel was also turned into a feature film starring Leonardo DiCaprio, Robert De Niro, and Ellen Barkin.

In order to fit the "look" of 1950s-era Concrete, the town itself was transformed back in time "Hollywood style" for the weeks that filming took place in 1992.
