The new Columbia Pike

The 1966 expansion of the tiny village of Columbia

U.S. Route 40 in Maryland

, US 29 had assumed its current shape. In 1968, the terminus of US 29 was diverted away from Baltimore; it was retracted to US 40 in Ellicott City and then moved north two miles (3 km) to MD 99

Maryland Route 99

, and an interchange similar to the one in place between US 29 and US 40 was built to connect the route with Interstate 70

Interstate 70 in Maryland

(then designated I-70N).

US 29 Freeway

Initially, the northernmost 2 miles (3.2 km) of US 29 were the only grade-separated limited-access segment of that route in Maryland. However, gradual construction of interchanges south of US 40, starting with Howard County's segment in the late 1980s and continuing to the 2000s in Montgomery County, has resulted in a full freeway between I-70 and MD 108, an almost-freeway between MD 108 and MD 216, and a partially grade-separated expressway between MD 216 and MD 650, with interchanges at Johns Hopkins Road and MD 216 completed in the early 2000s.
