 East of the Iowa River is the Meskwaki Settlement , which is home to about 800 Meskwaki Indians and the Meskwaki Casino and Resort . As it heads into the Tama – Toledo area , the expressway bisects the two communities . Between the two cities , it meets US 63 at a partial cloverleaf interchange . From US 63 it turns to the southeast to skirt Tama 's east side . It rejoins the former alignment of the highway east of Tama and heads due east , along section lines in Tama and Benton Counties , and does not enter another town for 40 miles ( 64 km ) .
