And this roadway is an expressway, not a freeway.  The new part will still have at-grade intersections in certain locations, but no signals except at Frederick Road and at the I-70 on ramps.

What about those flashing yellows like on 301 on the Eastern Shore?
I do not remember seeing any offhand.

Does the newly widened section of Route 32 have any "loons", as shown on the plans?

A loon is, according to http://www.cmtran.com/what-is-a-loon (a drawing and more details are on the page),
Quote
...pavement that is constructed outside of the normal traffic lanes to allow for larger vehicles to safely make a U-turn on a divided roadway.

There are apparently 1 or 2 of these bulb-like turning areas, each paired with the median breaks for the "Michigan lefts" associated with the remaining at-grade intersections.

A loon is also a cool-looking species of black-and-white waterfowl, but these are only found at more northern latitudes.

Yes, there are two sets of them. One set is at an un-marked "For Authorized Use Only" crossover north of the emergency half-intersection with the entrance to the SHA and Howard County maintenance facilities. The other set is at a fully signposted superstreet turnaround, and is located north of the Middle Patuxent River beyond the dual bridge spans over a small tributary of that river. The rumble strips are continuous across both sets of loons on both sides of the dual carriage way.

When MD-404 was 4-laned last decade, SHA called these “J-turns”.

My preferred term is "Michigan left", because I'm a native Midwesterner. But I think "loon" is a more creative one, since I never heard of it being used on this forum until now. (FWIW, Carpenter Marty Transportation, where the term "loon" came from, has offices in Columbus, OH; Charleston, WV; and Cincinnati, OH.)

I thought that the "loon" referred specifically to the additional, bump-out of pavement to help facilitate the U-turn associated with the Michigan Left.  They are not found, for example, on the 2 J-turns connected to MD-3/Crain Hwy. and Waugh Chapel Rd, since the roadways there are already wide enough that most vehicles can turn around without hitting the opposing curb or ditch.

I first read about the term loon in an ODOT report about a new superstreet section of US-35, now apparently home to the only remaining signalized, at-grade intersections between I-75 in Dayton and I-64 near Charleston, WV.

I’m a native Midwesterner as well, but we don’t call them “Michigan Lefts”.  Technically, they aren’t to begin with.

I drove that stretch about a month ago, at which point each direction of MD 32 was on the final carriageway but with the left lane coned off pending final paving & marking. Glad to hear it’s fully opened now.

I wonder if the I-70 interchange will ever be revisited in the future - IIRC, there were previously larger plans for that interchange before being slimmed down to simply a 2nd left-turn lane for MD 32 NB -> I-70 WB.

The outgoing Gov. Hogan is largely responsible for very pro-highway policies.  Toll reductions and highway expansions, including this project, are largely a result of his policies. 

I believe that very likely further improvements would have to be a priority of the next governor.  Improvements to MD-32/I-70 interchange are certainly warranted, but to be implemented, it would have to be a funding priority of the next governor.  I would venture to guess that if a Democrat wins the election, transportation funding would be more heavily focused on transit and alternative transit as opposed to roads.  While there may still be funding to complete projects already in progress and for maintenance (like repaving), I doubt that we will see new funding for expansion projects in a Democrat administration.

So if Wes Moore is our new governor, I don't think we will see improvements to this interchange or any progress on the 270/495 HOT lanes, but we will probably see some funding for East-West transit in Baltimore.

I thought Moore flip flopped to supporting the 270/495 toll lanes

I guess the official ceremony was today.  The opening was so three weeks ago  (https://www.aaroads.com/forum/index.php?topic=24933.msg2757174#msg2757174).   :D

Meanwhile a little further west on I-70 from MD 32, exit 59 is now a complete interchange as of Tuesday...the new eastbound offramp opened that morning (and I coincidentally drove thru the interchange later that day).

What an improvement! I was always irked by the lack of a complete interchange at this location. I understand why it was like that but I don't fully understand why it took this long to build the missing ramps. I suppose it had to do with the increase in development along Frederick Road east of the interchange.

The boldfaced is exactly why - my understanding is that MDOT SHA would have gotten around to it eventually, but likely not for several more years, if they had funded this themselves. However, both this new EB offramp and the WB onramp that opened a few years ago were funded by developers (presumably a condition stipulated in the approved traffic impact study for the continuing development around Oakdale High School).

2 Questions:

Is the Speed Limit on the MD 32 Freeway from I-97 to Columbia (still 55)?

Also, what is the Speed Limit on the new widened section (MD 108 to I-70)?

Yes, and mostly 55 but I believe that it reduces as it approaches I-70.

Since the newly widened portion was built as a non-limited-access highway, it would be restricted to 55 mph. Realistically, it can probably handle 70 mph, but state law would not allow anything over 55 mph.
