NB: As of Nov 29 the bridge work is completed and it is open to hikers. Jogging and bicycling are not recommended on the trail at this time due to major rutting that occurred.
From the
WMNF website.:
Lincoln Woods bridge to be replaced. The old railroad bridge, which crosses Franconia Brook where the Lincoln Woods Trail becomes the Wilderness Trail, will be replaced, with work starting October 29 and continuing to (the end of November) (2007).
Hikers using the Lincoln Woods and Wilderness trails from the south, and the Franconia Brook, Lincoln Brook and Bondcliff trails from the north, will be affected by the work and are advised to seek alternative routes, such as the Pemigewasset East Side Trail (formerly known as East Side Truck Road), and to use the Lincoln Woods suspension bridge if crossing the river from the south or the Wilderness suspension bridge from the north.
Those going to Franconia Falls will not be hindered by the construction, but should be alert as they may encounter vehicles on the trail. Caution should be exercised passing the project site.
