Why didn't the Keystone (Mill Gulch) bridge end up in Denver?

Not long ago, I posted a video (see below) showing the former South Park Keystone Bridge (also known as Mill Gulch Bridge) in Helen McGraw Tatum Memorial Park in Bailey, Colorado.  I found a little more background on why it didn't end up in Denver as planned (as discussed in this 1977 Rocky Mountain Rail Report).  The information came from pages 393 and 396 of The Mineral Belt Vol II -- Old South Park -- Across the Great Divide published in 1978 by David S. Digerness

"The road below the dam would make one crossing of the South Platte River at the location of the existing narrow-gauge railway bridge at Keystone.  That structure will be replaced with a steel-beam concrete-deck bridge, with a 22-foot running surface employing the existing bridge abutments.  It is planned that the historic Keystone bridge will be carefully dismantled, and each piece will be marked and stored at Kassler for future use whenever an appropriate site is located.

"It is interesting to note that the Keystone bridge was offered to the City and County of Denver by the Denver Water Board in the fall of 1977.  The bridge was to have been used as a pedestrian crossing on the South Platte River in the city – positioned so that the Auraria campus parking lot could have been used for public parking during Bronco football games.  However, the U.S. Bureau of Land Management (BLM) stepped in and said the bridge belonged to them and the Denver Water Board could not give it away because they did not own it.  It seems that when the railway abandoned their right-of-way, the bridge was left behind – and bridge, right-of-way and all reverted back to public domain administered by the BLM."

Some other info on the process of dismantling the bridge in 1978 can be found here from the Rocky Mountain Rail Report.

Following the C&S Ry. from St. Elmo to Alpine/Fisher-video

A few years back my family and my in-laws went to a Christian family camp called Trail West just outside of Buena Vista.  One day we were all taken on a jeep ride (we got to drive ourselves which was a blast) on a jeep road which ended in St. Elmo.  After a stop there to walk around and feed chipmunks we headed back via the old South Park right-of-way.  This is a video of the stretch east from just outside of St. Elmo to the townsite of Alpine, later renamed Fisher.  I mostly point out the spot on the line as noted in the railroad overlay on Google Earth (you can find this overlay on the dspphs.org site-It's an awesome tool!).  Unfortunately, I didn't know of many specific photos from railroad operation days except at Fisher.  At Fisher I put in some Then and Now images that line up fairly well with my view from our jeep.  

Enjoy!

Here's a video from farther east showing some of the grade from the Cascades area.

Central City 1977 footage

I found some interesting footage of Central City from 1977.  It shows the Colorado Central Narrow Gauge Railroad's boarding site apparently after hours or on a day off.  At first there are shots of C&S 71 and combine No. 20 on static display.  The focus then shifts to Shay No. 14 (this is the year that No. 40 followed No. 44 over to Silver Plume leaving No. 14 as sole power) and the rider cars for the tourist railroad there.  No. 14 arrived at the CCNG in 1974 from the defunct Camino Cable & Northern.  The Shay was purchased because of its ability to negotiate a sharp curve that the CCNG planned to construct to avoid rebuilding Mountain City trestle.
