U.S. 31 joins the Indianapolis beltway at Exit 2 near Edgewood. The US highway continues north along Meridian Street by Home Place to north Carmel. U.S. 31 represents a major corridor north from the capital city to Kokomo and South Bend. Because of this, three segments of the highway are being upgraded to freeways in the areas of Carmel and Westfield, Kokomo, and Plymouth to South Bend. With that, the current interchange with U.S. 31 is going to be changed to allow for free flowing traffic between the new U.S. 31 freeway and Interstate 465. 10/16/04, 12/11/11

Now 1/4 of a mile from Exit 21 (71st Street). From between 86th and 71st Streets on the east side of Interstate 465 is the sprawling Park 100 business park. The added commuters to the Park 100 area were the primary reason for the expansion of Interstate 465 on the northwest side. 12/17/11

The entrance ramp from both Interstate 65 south and 56th Street swells Interstate 465 to five lanes southbound as it approaches the next interchange at 38th Street (Exit 17).

Now a half mile away from Exit 17. Work at Exit 17 (38th Street) added a loop ramp from 38th Street eastbound onto the Beltway northbound and reconfigured the remaining ramps to turn Exit 17 into a parclo interchange. Exit 17, along with upcoming Exit 16; provide the best routes for southbound traffic to the Indianapolis Motor Speedway on Race day. 12/06/12
38th Street ventures west to Eagle Creek Airport and Eagle Creek Reservoir and east to Exit 119 off Interstate 65. From there, the road continues eastward as a major arterial that at one time carried SR 37 and SR 67. The new interchange complex of Exit 16 looms ahead in one mile. 12/06/12
South of 38th Street (Exit 17), Interstate 465 expands to six lanes as the right two prepare to turn off for Exit 16A with Interstate 74 west and Crawfordsville Road (U.S. 136 west). The original mainline of Interstate 74 stretches from the Quad Cities of Iowa and Illinois southeast to Indianapolis and Cincinnati. In Indianapolis, Interstate 74 will follow Interstate 465 around the west and south sides. 12/06/12
An older sign directs traffic for Crawfordsville to use Interstate 74 via Exit 16B and Speedway and Clermont to use Crawfordsville Road/U.S. 136 via Exit 16A. The sign dates from the former cloverleaf interchange that was Exit 16, but the designations are still true. 12/06/12
The original configuration of Interstates 74 and 465 saw a cloverleaf interchange with a freeway spur east to Crawfordsville Road (U.S. 136) and Speedway. Accelerate 465 road work removed the freeway stub and added a new direct connection to U.S. 136 west from the Beltway. Until the interchange was complete, U.S. 136, due to a quirk in the highway, was the last non-interstate highway to exist inside the Indianapolis beltway. New Exit 16 combines all movements into a new distributor roadway. 12/06/12
A view of the ramp onto Interstate 74 west to Crawfordsville, Danville and Champaign-Urbana, Illinois. U.S. 136 parallels the freeway along the same course, joining Indianapolis with Clermont and Brownsburg in the western suburbs. Crawfordsville Road into Speedway provides the most patrolled route for Race day traffic to the Indianapolis Motor Speedway. 12/06/12
Now traveling in the middle of the interchange complex at Interstate 465 and Interstate 74/U.S. 136 west/Crawfordsville Road, the flyover ramp from eastbound Interstate 74 to northbound Interstate 465 north can be seen. Through the interchange Interstate 465 carries eight lanes of traffic. 12/06/12
