Interstate 110 winds north through Baton Rouge, joining I-10 with Downtown, the State Capitol and Baton Rouge Metropolitan Airport (BTR). The urban spur provides a high speed route to U.S. 61 (Scenic Highway) leading north from Scotlandville in north Baton Rouge to southern Mississippi. The freeway carries six lanes north to Louisiana 19 (Scotland Avenue) and four lanes on the western leg to Scenic Highway. Speed limits are posted at 50 miles per hour on the substandard portion to the south and 60 miles per hour on the more linear stretches to the north.
A four level interchange joins Interstate 110 with U.S. 61 & 190 (Airline Highway) east of the Mississippi River Bridge. U.S. 190 and I-110 form part of an incident detour for I-10 and the Horace Wilkinson Bridge.
Initial construction for Interstate 110 took place by 1956 east of Capitol Lake and south of Memorial State. Named the Baton Rouge Expressway (Louisiana 3022), the short segment opened south to North Boulevard and north to Louisiana 67 (22nd Street) by 1961. The viaduct system south to Interstate 10 was completed by 1963, allowing a fast route from Downtown to the eastern suburbs and I-12.
Early plans for Baton Rouge outlined a full loop north from Interstate 10 using a portion of U.S. 190 (Airline Highway) and the Mississippi River Bridge. This included a new terrain alignment from I-10 north to U.S. 190 at LA 1145, and an upgrade of U.S. 190 east to a trumpet interchange with I-410 leading south to the Baton Rouge Expressway.

Extension of I-110 north to Airline Highway was completed by 1972. The freeway opened north from U.S. 61 & 190 to Harding Boulevard by 1978. The final link with U.S. 61 (Scenic Highway) was finished by 1984.
A number of sign changes were made along I-110 by 2003. This included the following exit renumbering:
Interstate 10 – unnumbered, new Exits 1I/J
Laurel Street – old Exit 1F, new Exit 1H
Evangeline Street – old Exit 4A, new Exit 4
Hollywood Street – old Exit 4B, new Exit 5A
U.S. 61 & 190 (Airline Highway) – old Exit 5, new Exit 5B
LA 19 – old Exit 8, new Exit 8A
U.S. 61 (Scenic Highway), old Exits 8A/B, new Exits 8B/C
The freeway was resigned again to use Clearview font by 2013.

The exchange with Interstate 10 is often congested due to the sharp turn I-10 makes between the Horace Wilkinson Bridge approach to the west and the curve southeast toward Louisiana State University (LSU). Photo taken 05/19/14.

Perspective from Interstate 10 west
Interstate 10 westbound elevates on a system of viaducts from the Louise Street off-ramp (Exit 155C) to the split with Interstate 110 north (Exit 155B). I-110 connects I-10 west with U.S. 61-190 Business (Florida Street) to Mid-City. Photo taken 05/19/14.
The westbound mainline of Interstate 10 bottlenecks to four overall lanes through the directional T interchange with Interstate 110. The freeway turns west to span the Mississippi River ahead of Port Allen. I-110 begins with a 50 mile per hour speed limit, navigating between Mid City and Downtown along a viaduct system. Photo taken 05/19/14.
Coupled with a sharp curve and 35 mile per speed limit for trucks, the substandard ramps at I-110 north (Exit 155B) add to the routine congestion during peak hour traffic or during accidents, construction or severe weather. Photo taken 05/19/14. Photo taken 05/19/14.

Perspective from Interstate 10 east
Interstate 10 ascends onto the Horace Wilkinson Bridge initially with two eastbound lanes. Flyover ramps from LA 1 at Port Allen expand the freeway east to three lanes to the left-hand ramp (Exit 155B) for Interstate 110 north in two miles. Photo taken 05/19/14.

Interstate 10 turns south from the forthcoming directional T interchange (Exit 155B) and advances four miles to split with Interstate 12 east. I-110 winds north through the city to connect I-10 with U.S. 61 north. U.S. 61 reaches Natchez, Mississippi in 90 miles. Photo taken 05/19/14.
Peak hour traffic congestion is a regular occurrence at Exit 155B due both to the lane drop for I-110 north and the sharp curve of the eastbound viaduct for Interstate 10 east. 2014 counts recorded by LADOTD showed 92,084 vpd along the I-10 mainline here and 19,528 vpd using the ramps to I-110 north and from I-110 south.
