Pumpkinvine Trailhead Development and Bridge Rehabilitation (Updated August 25, 2009)

Through the Lily Foundation and an Indiana Trails Grant, the Elkhart County Park & Recreation Department has continued the development and construction of the Pumpkinvine Trail. The County Park Board has commissioned Lehman & Lehman, Inc. to complete the design and development of a trailhead and parking lot as well as bridge rehabilitation.

The trailhead layout and design will be located east of State Road 13. It will include the development of a rest area equipped with picnic tables, benches, a drinking fountain and bike racks. In addition, the trailhead design will include an information kiosk about the Pumpkinvine Trail. Located off the west side of County Road 43, the new parking lot will serve users of the trail. It will accommodate ten vehicles and will have two spaces that are handicap accessible with easy access to the adjacent trail.

Bridge rehabilitation work will occur on three former railroad bridges. One spans the south fork of Pine Creek and the other two span Mather Ditch and East Lake Ditch. The bridge work will include bank stabilization and stream realignment as well as the replacement of existing piles, ties, back walls, and new decking, rail systems and concrete approaches.

Construction by bridge contractor, Beer & Slabaugh, is in progress. Bridge completion is scheduled for June. The completion of the trailhead is set for September, 2009 and the parking lot in 2010. Photos showing "Before", "In-Progress" and "Final" stages of construction for each of the three bridges, parking lot and trailhead are below.
