The Henry Thompson Bridge was built in 1916-1918 and so named for the Scottish immigrant, local settler, and Skagit County Commissioner who promoted its construction. At the time, its graceful arch was the longest single-span cement bridge in the world, and it is currently listed on the National Historic Register. Until 1972, when the Washington State Department of Transportation re-routed Highway 20 outside the town, the Thompson Bridge was the connecting thoroughfare across the Baker River and into eastern Skagit County.
When the Lower Baker Dam was completed in 1925 and two years later raised to , it was the highest hydroelectric dam in the world as of 1927. It is currently owned, operated, and maintained by Puget Sound Energy.
The Historic Concrete Theater was built in 1923. Its stage has entertained audiences from vaudeville to boxing matches to silent films and later what was considered "the talkies". Recently it has reopened to host local bands and show second-run film releases. It is listed on the State Registry of Historic Sites and is reportedly host to a few "other-worldy spirits" that visit on a regular basis. The official website for the theatre can be viewed at: http://concretetheatre.net/ 
Concrete High School was built in 1952 with the typical and necessary scholastic appointments and one visible and unusual difference: the center of the school was built over the road leading to it. In order to make the best use of the property, the design incorporated the use of South Superior Avenue (the only street leading to the property) as an area to load and unload school buses out of the often inclement weather. The building took the place of the previous high school building in the center of town off of Main Street which still stands today. Concrete High School maintains a website found at http://www.concrete.k12.wa.us/hs.html
Shepherd of the Hills Lutheran Church hasn't always been a church. Its beginnings were, in fact, as a hospital built in 1909 in the "Cement City" area east of the Baker River. Built by Dr. E.F. Mertz, the doctor and his wife lived in the second-story residence and maintained the hospital facility on the first floor. Dr. Mertz was the only doctor in eastern Skagit County for many years as well as for both the town's cement plants. In 1929 the hospital was remodeled to be a grand mansion complete with hardwood oak flooring, mahogany woodwork, imported mural and flock wallpaper, crystal light fixtures and hot water heat radiators in each room. The mansion was then furnished with antique and custom-built furniture and soon became a show place where the Mertzes entertained both local and distant visitors. When both the doctor and his wife had died by 1945, the home, property, and contents was put up for auction and purchased for only $13,500 - well below the 1929 renovation price of $40,000. The purchaser, Concrete Herald newspaper owner and editor Charles Dwelley, sold the home and property in 1953 to the Evangelical Lutheran Church. The ELC then did extensive remodeling, adding a wing on the east room which would house the sanctuary. The new church was dedicated on Sunday, March 7, 1954 and is still in use by the incorporated Evangelical Lutheran Church in America.
Because the phone lines (as well the electricity) were out, the town's residents were unable to call neighbors, family or friends to verify that their fears were legitimate. Of course, the real story was not as fantastic as the fictional radio drama - all that had occurred was that the Superior Portland cement company's electrical sub-station suffered a short-circuit with a flash of brilliant light, and all the town's lights went dark. The more conservative radio-listeners in Concrete (who had been listening to Charlie McCarthy on another station), calmed neighbors that they hadn't heard a thing about any "disaster". Reporters heard soon after of the coincidental blackout of Concrete, Washington and sent the story out over the international newswire and soon the town of Concrete was known (if only for a moment) world-wide.
On April 27, 2008 at approximately 2:00 p.m., the historic 'Old Grade School' building caught fire. Despite fire fighters' efforts, the building could not be saved. According to the Skagit County Sheriff's Department in a press release, two 11 year olds and one 12 year old boy were later interviewed and allegedly revealed that they had been playing with lighters and set a mattress on fire, claiming that they thought they had put it out before they left.
Though an initial attempt was made to remodel the exterior of the building with a "castle motif", this was abandoned, and the property had sat dormant for over 20 years. Firefighters from nearby Sedro Woolley, Burlington and other surrounding areas responded to help battle the blaze. Not able to enter the intensely heated building, they could only contain the fire within the concrete exterior walls and keep it from spreading to surrounding businesses and trees that are located just to the rear of the structure. Though the adjacent part of the former school building was not visibly harmed, the three story building—a long time landmark (and arguably an eyesore), was a complete loss.
Concrete has had its share of interesting characters—some famous, and some only locally known.
Two such locally known and enterprising females decided that they would help bring Concrete into the 20th Century in a before-their-time fashion. In 1912, sisters Kate Glover and Nell Wheelock set out to build and install the first phone service in eastern Skagit County. Nell climbed the poles and strung the lines; Kate took care of the switchboard operation. The phone service was equipped with hand-crank-style phones that would ring into the switchboard serviced by Kate. The service these two gave was quick and often personal. In the event that no one answered the line being rung by the operator, Kate or her niece would often promise to find them as soon as possible and have the call returned. When there was a problem with a line down, or a phone not operating properly, Nell would rush to service the problem. Naturally, with progress came change, and the sisters ended up selling their phone company to a larger company that based their service out of Mount Vernon, "downriver". Gone was the personal service and caring that the two sisters provided, but their names have remained legend in Concrete.
Another local notable is internationally-known author Tobias Wolff, who spent a large part his teenage years in the Concrete area. His memoir This Boy's Life chronicles his early life living in eastern Skagit County and attending Concrete High School (referred to as "Chinook High School" in the novel). The novel was also turned into the 1993 feature film (of the same name) starring Leonardo DiCaprio, Robert De Niro, and Ellen Barkin. Wolff's troubled and often turbulent world living in the area with his abusive stepfather is portrayed rather frankly in the movie, and raised some cries of protest from his stepfather's three children. The exterior scenes of Concrete (as well as some interior scenes) were filmed in Concrete and the surrounding area and a number of local residents were used as extras. 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.
One of the more famous locals is Liam Walsh, who has recently moved into the area from Ireland. Liam is an upstanding member of the thriving Irish community in Concrete and is rumoured to hold large "sessions" in his local residence, where tuborg is the beer of choice. Liam has a long and illustrious Irish history which includes being a member of the prestigious "Greystones Crew" who are known for their wild antics and notoriously delish lives in general.
The Old-Fashioned Concrete Fly-In is held around the end of July for one weekend and brings small aircraft and their pilots to Concrete Municipal Airport. Homemade, antique, and various other small aircraft are on display along with food vendors and souvenir booths. Frequently, helicopter and airplane rides over the Skagit River with spectacular views of Mount Baker and the North Cascade Mountains are available for a fee.
Cascade Days is a summer weekend celebration that offers live music, a parade, fire-fighter and logging contests, bed races, a chili cook-off, and historic-town tours. Once a celebration that offered a professional carnival, street dance and a festival queen contest, Cascade Days has a notorious past that caused the festival to be cancelled for a number of years due to brawls and drunk-and-disorderly charges given to more people than local law enforcement could handle. Starting in the 1980s the efforts of locals brought a new kind of celebration which changed its name from "North Cascade Days" to the "Concrete Good Old Days". When that festival was deemed to need a new face, the town decided that it would be appropriate to bring back some of the former flavor and re-adopted the name "Cascade Days" in 2005. Cascade Days is held annually the third weekend of August. More up-to-date information can be found at: http://cascadedays.com/ and http://www.concrete-wa.com/attractions.html
