The beginning of that paragraph explains exactly why (regardless of it's sanity) they did this: >Breezewood is a deliberately awkward transition between Interstate 70 and the Pennsylvania Turnpike, where they (almost) meet. Back in the 1950s, as I-70 was being built, a law prohibited spending federal funds to channel drivers directly from a free road to a toll road. The law was later overturned, but to comply with it, highway planners designed a looping interchange that lets drivers avoid the turnpike if they (hypothetically) want to. More detail from Wikipedia: >I-70 uses a surface road (part of US 30) with at-grade intersections to connect the freeway heading south to Hancock, Maryland with the ramp to I-76, which through this section is the Pennsylvania Turnpike toll road. According to the Federal Highway Administration the peculiar arrangement at Breezewood resulted because at the time I-70's toll-free segment was built, the state did not qualify for federal funds under the Federal Aid Highway Act of 1956 to build a direct interchange, unless it agreed to cease collecting tolls on the Turnpike once the construction bonds were retired;[11] a direct interchange would have meant that a westbound driver on I-70 could not choose between the toll route and a free alternative, but would be forced to enter the Turnpike. However, the Pennsylvania Turnpike Commission was not willing to build the interchange with its own funds, due to the expected decrease in revenue once Interstate 80 was completed through the state.[11] Accordingly, the state chose to build the unusual Breezewood arrangement in lieu of a direct interchange, thus qualifying for federal funds because this arrangement gave drivers the option of continuing on the untolled US 30.[11] https://en.wikipedia.org/wiki/Breezewood,_Pennsylvania#Unusual_I-70_alignment https://en.wikipedia.org/wiki/Breezewood,_Pennsylvania#Unusu...
