A study using data from several northeastern tollers before and after E-ZPass electronic toll collection (ETC) finds the reduced tailpipe emissions from free flowing traffic produces a marked improvement in infant health.

Pennsylvania Turnpike Commission will be issuing an RFP shortly for a planning study of the future of their Allegheny Mountain tunnels. Two 2-lane tubes 1850m long they date back to 1940 and 1965. A study of alternatives in the 1990s concluded the tunnels should be abandoned in favor of a 67m (220ft) deep cut to the north of the tunnels.

Diversion from the tollroad to the parallel free road is an issue in southwest Maine, as in other places. In Maine they've just studied it again. HNTB ran surveys for the Turnpike on the nearby free roads and at the York toll plaza to establish how many people are taking the free road to avoid the toll.

The 183A tollroad on the northwest fringe of the Austin area is creating significant benefits for users and non-users alike. A survey based on before and after trip time measurements was done by HNTB for the toller Central Texas Regional Mobility Authority (CTRMA).
