I was way over in Cleburne yesterday for a day of floodplain management trainings, and decided while I was there to take walk :3 while there, I found a low water crossing with pipe arch CMPs (see my post on CMPs lol) which had a set of manual flooded road gates (remember, turn around don't drown!)

a vented low water crossing along Buffalo Creek with five pipe arch corrugated metal pipe culverts and riprap along the nearest bank. the road apron wall next to the riprap is visibly in disrepair, and the water generally still/ponded. in the background, a red ductile iron pipe (maybe 36") crosses the creak above the water (a wastewater aerial crossing!) and follows the creek along the opposite bank. A manhole structure can be seen behind the LWC, and more ductile iron pipe is exposed on the opposite bank just downstream of the crossing.a head-on view of the upstream end of the LWC. debris can be seen in the culverts, and some channel erosion seems to be taking place. a trio of ducks (possibly muscovy?) stand in the ponded water upstream of the culverts.a view along the neighborhood street before the LWC. one of the flood warning gates is on the left (a simple metal bar gate) with a bright orange sign that reads "ROAD CLOSED TURN AROUND DON'T DROWN"

I had to force my bf to pull over this morning when I saw a huge CMP used as a pedestrian tunnel! unlike smaller pipe culverts, these larger pipes are made of modular structural plates that can be fashioned into a variety of shapes! this one, for instance, is a slope-mitered horizontal ellipse!

a view from one end of the CMP tunnel, which runs through a ~8' embankment with a driveway running overtop just out of view. note the two grate inlets on either side of the asphalt path (one of which is thoroughly sedimented).a view looking down the inside of the tunnel, standing approximately 6.5-7' tall. the bolts that hold together the structural plates can be seen running down the length of the tunnel, as is a set of overhead fluorescent lights. a thin layer of asphalt on the bottom provides a level walking surface.a view from the other end of the tunnel on the other side of the embankment. note the two grate inlets again, this time with much less sediment and debris!

went to check out some of the old rail bridges around White Rock Lake! first shown in the SoPac/Williamson Branch trestle (barely 1' below the new SoPac trail bridge!), then the former ATSF/GC&SF Overpass (over the Santa Fe trail), and lastly the still in-use KCS/CPKC bridge over White Rock Creek!

another fun thing I found out: this wasn't Minneapolis' first set of unique manhole covers! in the 1980's, the Artist Designed Manhole Covers project featured cover designs from 11 artists on 6th & 7th St. (hehehe) with the theme "entertainment in Minneapolis"

I've been meaning to post about this from the FM trip, but I wound up doing a lot of reading about it so this post got a little delayed lol but one of the really neat things I saw around the Nicollet Mall were these very detailed covers of Minnesota's state flora/fauna and grains of the Midwest!
