The Bridger-Teton National
Forest is making progress on replacement
of 3 bridges in the Pinedale area. Crews
are scheduled to begin work on the Sweeney
and Half Moon bridges on the Half Moon
Lake road in early September.
The Union Pass road and Tosi bridge are
open to vehicle traffic, and the Tosi bridge replacement
is expected to be complete in mid-
Construction crews will soon be mobilizing
to the Half Moon Lake road for the replacement
of the Sweeney and Half Moon
bridges. Both the project manager and Pinedale
Ranger District personnel have been in
contact with local land owners in the area,
with the goal of mitigating access impacts.
The Half Moon Lake road is scheduled to
close for approximately two to three hours
on Sept. 5 to unload and pre-stage the bridge
components. The Half Moon Lake road
below the campground close beginning Sept.
9, when the contractor will begin excavation
at the Sweeney bridge site. Once the new
Sweeney bridge is constructed, the contractor
is scheduled to mobilize to the Half Moon
bridge site on Sept. 16.
As part of the mobilization to the Half
Moon bridge site, the Half Moon Lake road
will be closed at the junction with Skyline
Drive. No access will be permitted through
the construction sites to ensure the safety of
the workers and the public. Full closures of
the Half Moon Lake road are scheduled to
end by Sept. 27.
Hazardous conditions associated with construction
of the new bridge abutments on the
Tosi bridge had forced a closure of the Union
Pass road to through vehicular traffic during
the month of August. Though the road is now
open, travelers can expect to experience short
intermittent closures of up to two hours at the
Tosi bridge. Longer delays will occur when
crews are setting the new bridge deck with a
crane and building the roadway approaches.
The existing bridge will be used for travel
until the new bridge is finalized. Travelers are
urged to use caution as they proceed through
the construction zone, both for their safety
and for the safety of the construction workers.
