Interstate 35 (I-35) is a north–south
Construction of I-35 in Iowa took place over 17 years. The first 10-mile-long (16 km) section of the route that stretched from Cumming to Urbandale was opened on September 21, 1958. In the next 14 years, new sections of the route opened regularly, only leaving the section between Mason City and US 20 uncompleted. On November 14, 1975, the last 50-mile-long (80 km) section of the route was completed and connected the two noncontiguous sections of I-35.
Route description
Southern Iowa
I-35 enters Iowa at the
The Osceola area is served by three interchanges for I-35. The first is a partial cloverleaf interchange with US 34. This junction is so configured because of US 34's proximity to the BNSF Railway line, which carries Amtrak's California Zephyr.[4] The next exit for CR H33/Kansas Street serves a casino and western Osceola. Northwest of Osceola is the western end of Iowa 152, which connects I-35 and US 69 at a narrow point between the two routes. Further north, the small towns of New Virginia, Truro, and St. Charles are each served by an interchange. The Iowa 92 exit just east of Bevington connects I-35 to the larger communities of Winterset and Indianola, to the west and east, respectively. The interchange for Cumming is the last before the Interstate enters the Des Moines metropolitan area.[1]

The first rest areas along Iowa's Interstates were built in the 1960s. They were modest facilities; separate buildings housed the restrooms and vending machines. A few rest stops had another building with local tourist information.
Transit
Jefferson Lines provides intercity bus service along the length of I-35 in Iowa serving seven communities along the route. The Des Moines Bus Station serves as a major transfer point along the I-35 route.[11]
History
The first section of I-35, a 10-mile-long (16 km) stretch from Cumming to Urbandale, opened around September 21, 1958. Within five years, the Interstate had grown to 55 miles (89 km), extending from US 34 in Osceola to the eastern interchange with I-80 and I-235. The next two sections of I-35 were the 25 miles (40 km) from Ankeny to US 30 near Ames and the 30 miles (48 km) from Ames to US 20 near Williams.[2]
By 1972, I-35 was completed at the Missouri and Minnesota state lines. In southern Iowa, the last section, from Iowa 2 near Decatur City to the state line, was completed on December 2, 1970. In northern Iowa, the section from Iowa 9 near Hanlontown to the state line opened on December 12, 1972. The last section of I-35 to open, from US 20 to Mason City, opened on November 14, 1975.[2]
