Background:
- Used as a migration route for Alaska Natives
- The Portage Pass Trail is two mile long hike which provides views of both Portage Glacier and Passage Canal
- This trail is used mainly during the summer months.
Purpose:
The purpose of this project is to develop the primitive trailhead to an improved Level of Service
Existing Conditions caused by over usage:
- Road and Parking area in poor condition
- Insufficient parking capacity
- Lacks sanitation facilities and amenities
- Failing double culvert crossing
- Has an unsafe non-standard railroad crossing
Design Considerations
The final Design shall improve and expand visitor facilities by providing:
- Safer railroad crossing
- Parking to accommodate 55 vehicles and 7 oversized
- Double Vaulted Toilet
- Picnic Pavilion
- Trailhead featuring interpretive signs
- Removal of the existing culvert stream crossing
- Installation of Pedestrian Bridge
Scope of Work
- Trailhead Accommodations
- Parking Lot
55 parking spaces
7 over-sized vehicle spaces
expansion room - Visitor Facilities
Double Vaulted Toilet
Pavilion with 2 picnic tables
interpretive signage
2. O’Neill Crossing (Bridge)
- removal of double culvert crossing
- pedestrian/vehicle bridge
low maintenance
Cost Effective
3. Railroad Crossing
- Analyzing existing design and reasons for improvement
- Limited signage
Design Alternatives
Alternative #1
Pros:
- Expandable, low maintenance daily use area
- User friendly accommodations (restrooms, picnic, oversized vehicle parking)
- Isolated near existing trailhead to reduce interactions with neighboring property owners
Cons:
- Vehicle bridge cost
- Maintenance of bridge and approach road
Estimated Construction Cost: $2,100,000
Alternative #2
Pros:
- Proximity to trailhead
- Capacity for expansion
- Pedestrian bridge
Cons:
- Potential wetlands
- Potential floodplain
Estimated Construction Cost: $1,100,000
Alternative #3
Pros:
- Pedestrian Bridge
- Maintenance of bridge and parking lot
- Room for expansion
Cons:
- Lowest elevation, possible flood plain
- Farther from trailhead
- Potential vehicle-pedestrian conflict
Estimated Construction Cost: $1,200,000
