On the other end of town, the Rock Island Bridge is under reconstruction to accommodate pedestrian traffic to the President Clinton Center. The structure was originally built in 1899, however the lift span was not added until 1972, 8 years before The Rock went under.

The rather large head house of the Rock Island Bridge, as viewed from the Little Rock side of the river.

Union Pacific's Junction Bridge is the middle of the 3 lift bridges in downtown Little Rock. It was last used in 1985, and has since been converted to a pedestrian bridge in the permanently raised position. Stairs and an elevator allow people to cross the raised section. This bridge sits directly in downtown,  and is an integral part of the development of the city's 6 bridge plan. A large park, amphitheater, and mass of walking trails along the riverfront is accompanied by a trolley line and cluster of downtown bars and restaurants.

The death of the Rock Island led to the abandonment of both the Rock Island bridge and the ex-MoPac Junction Bridge.  Whle the Rock Island was still alive, freight out of MoPac's huge North Little Rock yard used this bridge to go to Alexandria LA and Lake Charles..  When there was still a Lake Charles section to the Texas Eagle, it came out of the north end of MoPac's Little Rock station taking a very slow track along the riverfront and connected to the track off this brige just south of the south end of the bridge.  
 
After the Rock Island's death, MoPac took over their tracks in Little Rock and built connections using their line through Biddle Yard to access their line to Louisiana.  Longer that their own line across their Junction bridge, but probably as fast or faster, and eliminating the riverfront track and the bridge.  The tie in to their original line is just south of the end of the runway of the Little Rock airport.
 
All rail traffic crossing the river at Little Rock is now Union Pacific, and uses the double track Barings Cross bridge.

Thanks for the info, Mr. Harris. I had been researching the history of the lines and had not quite gathered enough to present it yet. As for the Rock Island bridge, it is being rehabilitated like the Junction Bridge for pedestrian traffic. The Clinton Presidential Center is right at the Little Rock end of the bridge, and both the ex MoPac and RI bridges are valuable links to North Little Rock.

Some more info on the railroad bridges of Little Rock:
 
The Baring Cross Bridge
 
In 1872 the Cairo & Fulton Railroad announced a bridge over the Arkansas River to connect their northern and southern divisions.
 
In 1873 the single track bridge opens with 4 truss spans and one swing span, with a roadway running along the top of the box-style truss spans. The road bridge was later moved to the rail deck. This bridge was the first permanent structure across the Arkansas River.
 
In 1927 the swing span and a truss span were wiped out during the massive flooding that affected the Mississippi and Arkansas Rivers.
 
In 1929 the bridge was reopened under the Missouri Pacific Railroad. Reports vary on the type of bridge.  
 
In 1967 the bridge was once again rehabilitated by Missouri Pacific under the guise of the McClellan-Kerr Arkansas River Navigation System, which required new height and width clearances on lift spans.  
 
After the Missouri Pacific and Union Pacific merger, UP continues the use of this double track bridge today, as it funnels directly into the Jenks shops and the North Little Rock yard. Amtrak's Texas Eagle stops at Union Station, just a few hundred feet south of the bridge.
 
It's interesting to note the conversion of the swing span to a lift span. As I have time, I will get more information on the other two bridges.

Another bridge:
 
I may decide this one belongs elsewhere.  The bridge is the ex-L&N memphis line bridge over the Cumberland River at Clarksville TN,  Still in use, which I did not know.  Now R.J.Corman.  Being rehabbed.

Good post on that RJC line bridge, I wish I had my own car here on this project to check it out, I'm an hour away...
 
I have a few shots from a trip to Ashtabula, OH earlier this year of the NS lift bridge on the entrance to the harbor lifting and lowering for a yard job.

On the other side of the canal, NS 6699 and 5050 work a coal train through the yard throat and reverse back to be dumped for export.

After an automated alarm sounded alerting boaters to the bridge moving, it slowly raised.

A very odd swing bridge over the Conneaut River at the P&C Docks in Conneaut, OH. Double track, with what appears to be road lanes retrofit in on both sides of the main span.

A seemingly rare example of a Scherezer Rolling Lift Bascule Bridge, the first of this type I have seen in person. North of Hazelhurst, GA on an ex-Georgia Florida Railway line, this bridge is over the Altamaha River.
 
This line is Georgia DOT owned, and several portions are still operated on. This segment is out of service, although the structure and rails are intact, with a derail affixed several hundred feet south of the approach span.
