[Python] LAB: Interstate highway numbers

I have a assignment to write a program that takes a highway number as input and outputs whether the highway is primary or auxiliary, goes east/west, north/south, and if it is auxiliary, what primary highway is it serving. Here is my code:

highway_number = int(input(''))

if highway_number >= 1 and highway_number <= 99:
prim = 'is primary,'
if (highway_number % 2) == 0:
print('I-', highway_number, prim, 'going east/west.')
else:
print('I-', highway_number, prim, 'going north/south.')
elif highway_number >= 100 and highway_number <= 999:
aux = 'is auxiliary,'
if (highway_number % 2) == 0:
print('I-', highway_number, aux, 'serving I- %d, going east/west.' % (highway_number%100))
else:
print('I-', highway_number, aux, 'serving I- %d, going north/south.' % (highway_number%100))
else:
print(highway_number, 'is not a valid interstate highway number.')


But if I run it. It adds a space between the "I-" and the highway number.
