The Village of Glen Ellyn is pleased to announce that the construction of the Taylor Avenue Pedestrian Tunnel project is anticipated to begin on August 13th, 2018.
About The Project
The project, located on the east side of Taylor Avenue at the existing underpass of the Union Pacific Railroad West Line, will create a grade-separated pedestrian crossing of the railroad to provide safer and enhanced bicycle and pedestrian accommodations. Additionally, it will improve vehicular maneuverability through the existing underpass by removing the sidewalk and maximizing the roadway width. This element is particularly relevant for access of public safety vehicles.
Recently Completed Work
In order to stabilize the railroad embankment while boring the tunnel, steel sheeting has been driven into the ground on the north and south side of the tracks. From there, additional bracing has been attached to hold the two rows of sheets together for when the contractor starts to remove the outer portions of the railroad embankment.
Current and Upcoming Work
Railroad Embankment Removal
After installing the reinforcement system, work is primarily focused on digging out and removing the excess soil from both sides of the tracks.
Once the embankment has been removed, the contractor will be able to bore tubes through the railroad embankment for the grout injection. The injected grout will fill any tiny cracks or voids in the soil beneath the tracks. This will significantly stabilize the soil and help prevent movement of the tracks during the tunnel boring process.
The tunnel boring process will begin on the north side of the tracks and end on the south side. In order to give the boring machines room to operate, the contractor will dig a jack pit on the north side of the tracks. This will provide a level and stable base from where the boring operation will be staged. Starting mid-month, a pit will be dug and a concrete pad will poured to provide the staging area.
Recently completed work
On August 13th, Taylor Avenue at the Union Pacific Railroad bridge was closed and the detour was set into place. Along with the closure, a chain-link fence was erected to provide the workers and local residence an increased level of safety during construction.
All trees and brush was removed from around the railroad to provide a room for the upcoming tunnel and path.
South Reinforcement Sheeting
Successful coordination with ComEd resulted in temporarily dropping the overhead power lines south of the rail road. This gave the contractor a narrow window to install temporary sheeting along the south tracks to stabilize the railroad embankment for the upcoming tunnel boring.
Current and Upcoming Work
North Reinforcement Sheeting
Currently working on installing the north portion of sheeting to stabilize the railroad embankment for the upcoming tunnel boring.
Additional Railroad Embankment Reinforcement
Once the north side is complete, the contractor will begin excavating the soil outside of the newly installed sheeting. This will enable the installation of the final railroad embankment reinforcement measures to ensure stable conditions for the upcoming work.
