Steve, Mount Clemens, MI is the county seat of one of the largest counties (Macomb) in MI. In the mid-70s, they built a pedestrian mall smack in the middle of downtown and closed 4-6 blocks, which quickly killed what used to be a thriving, traditional “main street” town center. In the mid- to late-90s, they reopened it and are crawling back back from that ill-advised brink. I'll try to find links for you, but with a population of only about 20k in the city proper, it might not hit the population threshold you might need?

I live in Williamsburg, VA, and we have a “sort of” pedestrian mall. We have a main road (Duke of Gloucester street/DOG street) that's closed to traffic that's about a mile long. It runs through an area mostly (but not quite completely) owned by The Colonial Williamsburg Foundation which contains a large scale recreation (buildings and actors) of the colonial city that used to exist here. There are also several side roads that are partially closed in the area.

There are also a few remaining private homes, some active churches, about 3 blocks at the west end of the street a modern (but carefully planned to look like a downtown) shopping district, and many of the “colonial” buildings actually contain apartments for employees of the historic foundation.

What makes it a “sort of” pedestrian mall is the fact that one can sometimes park and/or drive on the street at certain times of day. (Generally, after 10:00 PM and Before 5:00 PM. Also, if one is going to a specific business, for example, that only has on street parking on the mall). But it is illegal to drive down the street/through the area without stopping during the day – and there are gates that one must get out of the car, open, move the car forward, and then close manually behind oneself on many parts of the street.

There's also a decent push by local merchants to close more of the side streets

Steve,

What info do you need about DC?

In Elgin IL, it looks like Wellington Avenue and Ziegler Court were once a rail line, and there are a couple of random blocks of Ziegler that are still mall-like, without cars and with “improvements”.

Ah, my hometown: Dubuque, Iowa, Town Clock Plaza, built 1971, completely closed Main St. to traffic between W 5th and W 9th Streets, 4 blocks total. Reopened to traffic August 2002. No concrete canopies.

Sources:
Built date: http://www.encyclopediadubuque.org/index.php?ti…

Opening date: search of http://www.thonline.com archives for the phrase “town clock plaza open traffic main”. Resulting story had this quote: “The ceremonial opening occurred in August 2002.”

Both sources have good ancillary information on the impact to businesses of both moves… the original plaza displaced 65 businesses.

Google Street View also has nice pictures of the now-open Main St. The reopening still preserved some nice streetscape with additional sidewalk tables/benches, but fewer trees.

There is also such an animal, seldom trafficked and often avoided, in Portsmouth, NH: the so-called Vaughan Street Mall, formerly — of course — Vaughan Street. It's what you pass through after you park your car to get to the main street.

Chicago has had a pedestrian mall. Either on State Street in downtown or in the Englewood neighborhood. Neither exists. The Englewood neighborhood in fact had at 63rd and Halsted regular car traffic routed around the shopping area and you will see evidence of that still today. But some might say that if in the 1960s Chicago had never used that plan, the Englewood neighborhood might be in better shape today.

Steve, there is a book, For Pedestrians Only by Roberto Brambilla and Gianni Longo that list 70 malls, (Whitney Library, Watson-Guptill Publications 1977) some of which you still have in red. It has at least a paragraph and basic information on each one, including contact information (no doubt dated). The book itself, while it contains other information is basically a treatise on creating these kinds of spaces. You may already know the book, but if not it may be useful.
There is in depth information and analysis on a number of malls, including several you still have in red.

Steve,

What information do you need for Toronto, ON? Off the top of my head, I cannot think of any pedestrian malls besides The Path (underground mall). I have been to the one in Ottawa and I must say it is horrible but feels pretty European.

New London, CT has had its -a stretch of road known as Captain's Walk – removed for many, many years. All that remains are some curb.

I believe someone already mentioned it, but my hometown of Charlottesville, Virginia, converted Main St. to a pedestrian mall years ago. It’s still thriving! The street is lined with shops and restaurants (Charlottesville locals love their food), but I think one of the main reasons that it has had such success is that during warmer months, an amphitheater at one end of the mall hosts bands on Fridays. These are called “Fridays After Five,” and they bring a lot of traffic to the mall. When you go downtown on Fridays you’re are guaranteed to see people that you know. There is also an Omni Hotel on the other end of the mall, so visitors to Charlottesville explore the downtown mall (as it is called in C’ville) and spend money in the expensive shops that line the street.
