Before and after surgical crown removal by Coalition volunteers. October 2004 and August 2005.
Same dates, but other side of the overpass.
The Coalition determined that it is not practical to surgically remove kudzu along the top of the overpass: The railroad embankment is too steep for volunteers to safely reach kudzu, especially as this road is always busy with traffic. Several applications of rock salt failed to kill the kudzu. An herbicide was applied by the city at the request of the Coalition, with results shown below (first photograph is before, second photograph is after). This is one case where chemical control is the only realistic option. August 2006.
Looking good! Notice that the railroad installed an I-beam over the tunnel (on both sides). We suspect that these were put there to prevent gravel from falling onto traffic, or perhaps to limit erosion. It is a big help to us, because we can now safely get to any remaining kudzu. March 2007.
