In case you missed it last week, the Peaks to Plains Trail received air time during Colorado Public Radio’s story on Governor John Hickenlooper’s Colorado the Beautiful Initiative. Follow the link below to read or listen to the story.
The crews have been hard at work of late and have made great progress on the bridge abutments for 3 of the 4 future bridges. The actual bridges will be installed in late winter of 2016, but these abutments really start to give you an idea of what the finished trail will look like.
Step 1: Bring this huge track mounted drill up the canyon.
Step 2: Drill 2 caisson holes down to bedrock. No easy task with all the large cobble found throughout the canyon.
Step 2: Little by little.
Step 3: Pour concrete footers on top of the caissons.
Step 3: The concrete must cure before the area is back filled.
Step 4: Once the footer is back filled, the framing for the abutments goes up.
Step 5: Bring a pump truck in and pour the abutments. Each abutment requires two concrete trucks.
Step 6: Strip the forms off and wait.
Now you can really get a feel for the final elevations. The bridge will sit in the notch and the final bridge deck height will be even with the top of the walls on the sides.
