Route description

SH 42 begins in northwestern Lafayette at a junction with SH 7 (Arapahoe Road) and heads south on 95th Street. later, after crossing Baseline Road, the roadway S-curves to the east to line up with 96th Street, though it keeps the 95th Street name until the Louisville city limits. After bypassing downtown Louisville to the east, SH 42 turns east onto a road that becomes Empire Road upon leaving Louisville. It ends at US 287 south of downtown Lafayette.

History

State Highway 168 was designated in 1932-1934 along a route similar to the present SH 42, but using a number of different roadways. It began on SH 7 in the same place and headed south on 95th Street, but the S-curve was not in place and it jogged east on Baseline Road to reach 96th Street. SH 168 then jogged west on South Boulder Road across the railroad to Louisville's Main Street, and turned east on Pine Street, crossing SH 42 onto Empire Road. This street curves south to meet SH 42 at the current city limits of Louisville, after which SH 168 followed SH 42 to end at SH 1 (now US 287).

Two new segments of road were built in about 1970, giving SH 42 its current shape (but initially a sweeping curve carried traffic around the corner east of downtown Louisville).
