In October 1882, the New York, Chicago and St. Louis Railroad opened.
This railroad, which largely ran parallel to and south of the Lake Shore and Michigan Southern Railway (the former Cleveland, Painesville & Ashtabula), passed through the Village of Euclid Creek, making it an important stopping point again.
The railway, whose nickname was the "Nickel Plate", built a Howe truss bridge over Euclid Creek.

In 1895, the city of Cleveland and Cuyahoga County began converting Euclid Avenue from a plank road into a modern paved street.
The road was widened to 100 feet (30 m) and paved from downtown Cleveland to Village of Euclid Creek.
The project reached Collamer in 1902, and work on the final segment to the Village of Euclid Creek began in the summer of that year.
The work was finished in 1902, when a new masonry arch bridge was constructed to carry Euclid Avenue over Euclid Creek.

Swedish immigrants constructed a Lutheran church on the banks of Euclid Creek south of Anderson Road at Green Road in 1898.

Henry Pickands, a partner in Pickands Mather and wealthy heir of Samuel Mather, purchased in 1902 25 acres (0.10 km²) of land atop Chardon Hill (an area now bounded by Chardon Road, the Euclid Creek Reservation, and E. 221st Street).
In 1903, work was finished on a "Flemish baronial" brick mansion which he named Chestnut Hills.
His widow had Chestnut Hills demolished in 1938, and a Neo-Georgian style home erected on the site.

In 1907, a $10,000 ($300,000 in 2019 dollars) masonry bridge was constructed to carry Lakeshore Blvd.
over Euclid Creek.
This was followed in 1908 by a $15,000 ($400,000 in 2019 dollars) concrete bridge to carry St. Clair Avenue over Euclid Creek.
This bridge was a large one, 80 feet (24 m) long and 52 feet (16 m) wide, with a 45-foot (14 m) high arch.

The first major development south of the Euclid Creek gorge occurred in 1909.
That year, a significant number of members of the Euclid Club in Cleveland Heights quit and founded the Mayfield Country Club in Lyndhurst.
In July, they purchased an initial 88 acres (0.36 km²) of land about 0.24 miles (0.39 km) northwest of the intersection of Cedar and Richmond Roads.
Within a year, the club owned 226 acres (0.91 km²), and had dammed Euclid Creek (which ran north through the club grounds) to provide water for the club's planned 18-hole golf course.
The club, reduced to 216 acres (0.87 km²), opened in July 1911.

A Neoclassical house of worship was erected by Nottingham Congregational Church on the west bank of Euclid Creek near Waterloo and Nottingham Roads in 1910.

The first of three bridges carrying Highland Road over Euclid Creek was constructed at the north end of the Euclid Creek gorge in 1912.
Cuyahoga County wanted to push Highland Road southwest through the Euclid Creek Reservation, but the onset of World War I delayed the start of construction until 1920.
A bridge over the east branch of Euclid Creek was built about 1922.
Most of the remaining construction occurred in 1924, although it was not until 1928 that the final portion of Highland Road (connecting it to Euclid Avenue) was paved.
Three Highland Road bridges remained to be constructed.
Automobiles used fords to cross the creek at these points.

The Village of Euclid constructed Central High School at 20701 Euclid Avenue on the east bank of Euclid Creek in 1913.
It was downgraded to a junior high school in 1949, demolished in 1967, and rebuilt as Central Middle School.

Although settlement and development had largely been contained to Euclid Creek below the Appalachian Plain, a few important changes were beginning to happen to the creek's headwaters.
In 1913, Cleveland attorney Charles K. Arter constructed Arter House on the east bank of the main branch of Euclid Creek on what is now Curbside Road in Lyndhurst.
The 22-room, Late Georgian mansion sat on an elaborately landscaped 65-acre (0.26 km²) estate.
The Arter children, Calvin and Charles Jr., donated the estate to the Sisters of Notre Dame de Namur in 1957, who converted it into the Julie Billiart School (a school for children with learning dis
