An RFP for the Triangle Bikeway Implementation Study went out this summer. Link:
Notice to proceed was scheduled for 9/27/2019. Not sure who was picked. Cool thing is that among the desired end products in the RFP is a “functional design(s) and a recommendation for a phased implementation approach from Trenton Road in Raleigh to the Park Center site at Research Triangle Park in Durham County”. That’s a much longer route with better connections than what was discussed in the N&O article you linked.
If I was the RTP Foundation I’d be getting behind this as a way to help RTP companies attract talent that has no interest in a long car commute.
I would consider working for an RTP company again if I could work from home 2-3 days/week and bike the Triangle Bikeway from Raleigh 2-3 days/week.
