Aside from the standard Interstate, US, state, and county road markers,
you will find several other markers along Iowa's highways designating scenic
and historic routes. If you have additional information or routes to add
to this list, please let me know.
Images for the Delaware Crossing and River Bluffs Scenic Byways and the Glacier Trail were provided by Jeff Morrison, and the image for the Glacial Trail Scenic Byway was provided by Mike Ehret.
In August of 1993, Iowa state officials designated four routes as "Scenic
Byways" as an attempt to boost tourism. The Grant Wood, River Bluffs, Western Skies, and Woodlands (later renamed Historic Hills) Scenic Byways were the original four. The Iowa Valley Scenic Byway was added in 1998, and on July 11, 2000, the Driftless Area Scenic Byway and Glacial Trail Scenic Byway (then known as the Old O'Brien Glacial Trail) were designated while two new segments were added to the River Bluffs Scenic Byway. The Delaware Crossing Scenic Byway was dedicated on July 14, 2002. All of them were marked by special "Iowa Scenic Byway" signs until the fall of 2011, when each scenic byway received its own unique marker. During that time the Lincoln Highway, Loess Hills Scenic Byway, and the Great River Road were incorporated into the state byway system. (The Great River Road's signage did not change because of its status as a multi-state scenic route.)
More information can be found at the Iowa's Byways official website.

the river). On June 15, 2000, the U.S. Deputy Secretary of Transportation
designated this route as one of 30 new National Scenic Byways in the
United States and one of two in Iowa. Signs designating it as one of
"America's Byways" were put up in October 2003.

This is an 84-mile route through southeast Iowa, passing through several
state forests and the villages of Van Buren County (including Keosauqua
and Bentonsport). It was known as the Woodlands Scenic Byway before it was renamed in April of 2006. The route follows:

Lincoln Highway Heritage Byway
America's original "Main Street", this route, designated in
1914, originally ran from Council Bluffs to Clinton in Iowa en route from
San Francisco to New York City. The entire route became US 30 in 1926, and that highway has gone through many alignment changes over the years. Many red, white, and blue markers were painted along telephone poles along this route. Starting in April 2011 the Iowa DOT began placing signs marking the Lincoln Highway as a state heritage byway. Several "loop" routes were also signed along alternate Lincoln Highway alignments.
I have set up a page of Lincoln Highway photos in the Photo Gallery,
while Jeff Morrison has his own Lincoln
Highway Photo Gallery featuring photos that were taken for his photojournalism class
in the fall of 2002. James Lin's Lincoln
Highway Page and the Iowa Lincoln Highway Association's official website have additional information on this route.

This trail in the Des Moines River valley commemorates the path of the 1835
U.S. Dragoons (the country's first mounted infantry unit). It starts with two
branches originating from Fort Dodge and Webster City that join near Stratford; from
there it runs through Boone and Des Moines to the Red Rock Dam between Pella and
Knoxville. The trail, which is roughly 200 miles long, contains several signed alternate routes.
A promotional brochure that was published in May 1994 contains a map of the route
and all of its alternates. Using that and the Iowa DOT's PDF county maps to pinpoint
rural street names and road surfaces (paved unless otherwise noted), the Dragoon Trail follows:
- Fort Dodge to Stratford, starting at the Fort Museum in Fort Dodge:
Kenyon Road, Avenue C, Avenue B, River Road, 235th Street, Riverside Trail, County Road P59,
County Road D33 through Dolliver Memorial State Park, County Road D43 (former IA 50) to Lehigh, County Road
P73, gravel roads (320th Street, McGuire Bend Road, 320th Street again, and
Washington Avenue), and County Road D54 to IA 175.
- Alternate between Otho and Lehigh: County Road D33, County Road P59,
and County Road D43.
- Alternate connecting the two branches: County Road D46 between County Road D43 in Lehigh and Big Bear Road in Hamilton County.
- Alternate south of Lehigh: County Roads P73 and D54 between 320th Street
and Washington Avenue. (The mainline runs closer to the Des Moines River, but the
alternate is paved.)
- Alternate along the Des Moines River (entirely gravel): 340th Street,
Skillet Creek Avenue, and River Road from County Road D54 to IA 175 west of the
Des Moines River bridge.

County Road E41, County Road R18, and US 30 to the junction with County Road R23/Story
Street in Boone.
- Boone to Des Moines, from US 30: County Road R23 (old IA 164) into Ledges State Park,
County Road E52 and a series of gravel roads (P Avenue, 260th Street, and Peach Avenue)
east of the park, County Road E57, County Road R26, County Road E62, IA 210 to Madrid, IA 17,
former and current IA 415 through Polk City, NW 84th Avenue west of Ankeny, NW 37th Street, Horseshoe Drive
past the Saylorville Lake Visitors Center, NW 37th Street again, NW Toni Drive, NW 66th

Avenue, SE 6th Street, Hartford Avenue, SE 22nd Street, Evergreen Avenue, SE 34th
Street, and Army Post Road to US 65.
*Water Street is no longer open to vehicles near Principal Park. The recommended route around it would be to continue on 2nd or 3rd Avenue, depending on the direction, then continue on SW 2nd Street to Jackson Avenue to SW 1st Street.
- "Bus Route": Follows Holcomb Avenue and Saylor
Road between 6th Street and Penn Avenue instead of Birdland Drive; this route probably
exists to avoid a low-clearance overpass on Birdland.

Avenues downtown, it follows Grand westward to 5th Street in West Des Moines; from there
it follows 5th Street**, Railroad Avenue, IA 28, Park Avenue, George Flagg Parkway, Fleur Drive, and Locust Street back to 3rd Avenue. It is only signed in one direction.
**On June 3, 2005, 5th Street between Vine Street and Railroad Avenue in West Des Moines was changed from a one-way street going south to a one-way street going north.

alternate routes both end at the Lake Red Rock Visitors Center at the south
end of the dam.
A separate 4-mile long "1835 Dragoon Trail", with different markers than the rest of the route, is signed along Old IA 163, Pella Avenue, L Street, C Avenue, D Street, and 3rd Avenue in Oskaloosa between IA 163 and IA 23.
Dvorak Memorial Highway
In the summer of 1993 this former auto trail in northeast Iowa, named
for Czech-born musician Antonin Dvorak, was resurrected with new signage.
The 36-mile route begins at the Minnesota state line and follows County Road V58 through Cresco to Protivin, where it follows County Road B16 (including the former IA 325) through Spillville and US 52 to its southern end in Calmar.
This is a former auto trail that was established in 1918 and registered with the Iowa State Highway Commission on September 6, 1921. It originally followed the general route of US 65 north of Hampton, a series of county roads between Hampton and Marshalltown, and the general routes of US 30, IA 146, and US 63 south of Marshalltown. A history of the Glacier Trail from the Iowa DOT can be found here.
The Glacier Trail is signed for about 25 miles through Hardin County along Business County Road S56 in Ackley, County Road S56 from Ackley to Eldora, IA 175 through Eldora, and County Road S62 south of there.
Herbert Hoover Highway
Originally designated in the 1920s as a spur from the Lincoln Highway
to West Branch (home of Herbert Hoover) and Iowa City, this 45-mile route was revived
by local promoters in 1987. It starts at the intersection of Clinton Street and Iowa Avenue, near the Old Capitol, and follows:
- Clinton Street, Market and Jefferson Streets (one-ways), and Rochester
Avenue out of Iowa City.
- County Road F44 and IA 38 from Iowa City
through West Branch to Tipton
- IA 130 and County Road Y14 from Tipton
to US 30 at Lowden
Hiawatha Pioneer Trail
This meandering route through Iowa, Minnesota, Wisconsin, and Illinois was created by the American Petroleum Institute in 1961. After several conferences with the four states' governors, including one in Amana in September 1963, it was officially dedicated on May 15, 1964. The trail in Iowa split into north and south routes in Toledo before they re-joined in Davenport. Both branches were marked on state highway maps from the mid-1960s through 1975. In June 2008 the Iowa DOT decided to abandon the trail since none of the four states were actively sponsoring it anymore and began removing the remaining trail markers, although some scattered markers remain along the route. More information about the trail's history can be found here.
The approximately 750-mile north branch followed:
