OH-315 numbered exits?

[Buck87]

I wonder how long it will take them to get all the way to Port Clinton with this, if that's even the plan.

Actually, just noticed today that the OH 2 Ottawa County exits already have exit numbers, but do not have mile markers. According to GSV it's been that way since at least October.

Going west starting at the Sandusky Bay Bridge, the exit numbers are:

125 - OH 269 north (signed as 125 A & B, with B being Bay Shore Rd)
124 - OH 53 north
121 - OH 163 (double trumpet signed as 121 A & B)
117 - OH 53 south
115 - OH 163 (half diamond, exit from westbound only)

So when it comes to exit numbers, all that's left to are the ones in Erie County from OH 269 south to OH 61.
