Just got off the phone with Kevin at Arlington Parks. Final "walk through" of the project between Route 1 and Mount Vernon Ave will happen on Monday (24 July). Barring any issues, that section will be re-opened shortly thereafter and detour removed. Keep your fingers crossed!
Also requested he put a work order in to smooth out the two "speed bumps", which are roughly 100 yards apart, just east of the 395 underpass. (They're not really speed bumps of course, they are actually badly executed cold patches that were done to address "settling" in a couple of seams after construction of the trail.) Hope he follows through.
