In the middle of the last century the southernmost section of the D&L Trail's Delaware Canal Towpath was severed by rail lines and US highways 1 and 13. Thanks to the work of Circuit Coalition member organizations, PennDOT and Amtrak several projects have been completed or are underway to reconnect these crucial gaps. In 2013 PENNDOT completed a passageway to provide a grade-separated crossing of US 13 in Tullytown. Since that time PENNDOT installed a short connecting segment across US 13 in Bristol Borough and in the spring of 2019 a large gap in the D&L Trail will be closed between Bristol and Morrisville with the construction of a new trail segment under Tyburn Rd and a new passageway through a Conrail embankment.
When completed there will still be a detour in Morrisville Borough until a crossing and a ramp is constructed at Bridge St. (PA 32)
