Cheap Bollard Upgrade

December 22, 2015 By: Tom Davis Category: Sidewalk Features

20151112_102421This post is not made as though it is day-lighting a new add-on to the old, tired, scared bollards. The intent is to show that the plastic sleeve can be a good solution and is chosen by owners of major high-rise, class A buildings. The sleeve certainly cleans up the dock entrance and makes it look far less like a war zone.

I am sure the architects would prefer a different color that the one shown here but …


Bike Lanes

December 22, 2015 By: Tom Davis Category: Amenities, Paving

The City of Houston’s Department of Public Works and Engineering converted a parking and vehicular lane to a dedicated bike lane as you see here. The lane is “isolated” from the vehicular lane by the long stripped dome shapes that we Texans–not surprisingly–call armadillos.Bike Lane on Lamar2

Note the special signage as well as the special traffic signals for bike riders. Look closely at the red lens as it shows a red bike rider.

I also noticed at one intersection it appeared t2015-05-01 07.39.43he bike signal turned green ahead of the vehicular green signal by several seconds. My traffic engineering buddies would call that preemption to allow the bike rider to get into the cross street before the cars start.

You can see the lane on Dallas St. in downtown Houston.

Click here to see a one-page paper about the lane, how it fits in the street and a location map.

How well they work will be interesting to watch.


Bollards on Bagby

Bollard bent at BagbyThe award winning new streetscape on Bagby south of Pierce St. in Houston includes a very substantial curving row of steel bollards to protect a large pedestrian area at the intersection of Bagby and Pierce.  This post is too share a great looking design and offer observations about the issue faced by whoever has to fix the one that served it purpose; i.e. stopped a vehicle from driving onto the sidewalk.

District D-20120331-00087.jpgAlexandria has a rich southern history although most of the very old structures were burned out during the Civil War by the North. These photos are here to provide a visual reference about how restored brick streets should look–at least in Alexandria.

Unusual Cracking of Crosswalk Pavers

And u2012-11-21 07.39.39.jpgnusual cracking has been observed in the concrete unit pavers either side of the crown of concrete streets. The crosswalks have been in service for 10-15 years and there are others installed at the same relative time that do not show similar cracking. The pavers are installed in recesses in a reinforced concrete street cross-section and placed on a 1″ deep sand bed with sand swept and vibrated in after placement to lock them in place.

A Bike Rack as a Word

December 11, 2013 By: Tom Davis Category: Amenities, Recent Posts, Sidewalk Features

Navigation bike rack.jpgThe Greater East End Management District has developed an alternative use for a wide esplanade on Navigation Blvd. just east of downtown Houston.  There will be more posts to hi-lite the good ideas but for the first post this one is about an unusual bike rack.

As you can see it is the word “lauGh” neatly cut from a sheet of steel, hot-dip galvanized and anchored in the concrete sidewalk. In this case the concrete was stained red and text was added to indicate it is a bike rack. I was told that initially everyone thought it was art and not to be used for securing their bike.
