Lou Corsaro pointed me to
Monmouth County's Road Plan. I of course jumped right to "potential county roads." Here's what they are considering:
* CR 13 "35 Overpass" - I guess they want to take Shrewsbury Ave. over 35, instead of the existing jughandle/signal, and tie it to the south. It says to "537 Extension" - I'm thinking this means that Shrewsbury becomes the fourth leg at the northern 35/537 junction, since the southern junction has 71 on it as well. Since 537 isn't listed, I'm assuming it's not an extension to tie 537 in and eliminate the concurrency. 13/35 is one of the busier intersections, so this will be an improvement, and the county funding it takes pressure off the NJDOT's limited funds.
* CR 11 "realignment" - Looks like they're taking the back parking lots of Monmouth Race Track and turning it into an Oceanport Ave. connector, eliminating the jog along Port-Au-Peck. This is a cheap job but I don't see a need for it.
* CR 55 "realignment" - CR 55 is a mostly four-lane eastern Freehold bypass, but necks down to 2 lanes south of NJ 33. That's more than .47 miles. I think this takes Edinburgh Drive and extends it northward as CR 55, around the east side of the Burkes Creek ponds. It's a start, but 55 should be four lanes and straight from 33 back down to 9. I think Edinburgh is part of those plans, leaving a chunk in the middle that remains unaddressed.
* CR 524 "realignment" - The only possibility I see for that is to head straight into Montgomery Drive. A solution in search of a problem.
* CR 526 Spur "Alanland Bypass" - The existing short road is a terrible misnomer, only leading from 526 (east) to 524/539 (northeast). Any sort of through traffic has to go and not go straight through Alanland. The limits of the proposed project, from 539 (southeast) to Mercer County line (anyone's guess), still don't yield an actual bypass for 526, but this is a "SPUR" route, so it's not expected to return to the parent. It seems that this extension will actually yield something useful, taking traffic from 539 (a major road) around toward Trenton. I can't tell whether this is only building the west half of the bypass (with Mercer cooperation), or everything from county line to county line. I've never seen plans for a continuation/completion of 526 Spur. For all I know, this can become the first circular route in the state.
