Chatanika River Bridge FAQs
Starting in early May 2019, HC contractors expects to begin rehabilitating the bridge deck on the
Chatanika River Bridge located at mile 11 of the Elliott Highway. During the first phase of construction,
there will be a width restriction and a regulatory speed reduction of 5mph across the bridge.
Overweight loads will be required to obtain a permit from the Division of Measurement Standards &
Commercial Vehicle Enforcement (MS/CVE) as usual and may be required to take additional precautions
while traveling over the bridge, such as slow speeds or traffic control. After the first phase is complete,
there will be a 96‐hour window during which the width restriction will be 20’6”. The second phase of
construction will begin directly after that window with width restrictions.
To ensure that your operations will run smoothly this summer, we encourage you to submit your permit
applications early!
Additional information about the Chatanika Bridge Deck Rehabilitation:
Why is this project needed?
The bridge deck of the Chatanika River Bridge is deficient and requires rehabilitation. The bridge’s
substructure is sound, so replacing the bridge deck will extend the life of this bridge without a total
replacement. Each bridge replacement and rehabilitation project along the Fairbanks to Prudhoe Bay
corridor will help ensure the safety of the traveling public.

Why didn’t you build a detour bridge?
DOT&PF design engineers looked through options for a detour bridge, but considering that the
bridge is adjacent to a state park and campground that would require right‐of‐way acquisition,
building a detour bridge was deemed cost‐prohibitive.
What are the traffic impacts when traveling over the bridge?
The Chatanika River Bridge will be reduced to a single lane while construction activities occur, you
can expect traffic delays at all times until the completion of the bridge. For more detailed
information, check AlaskaNavigator.org for continual updates of traffic impacts for the entire Elliott
Hwy MP 0‐12 project.
Will the width restrictions affect the general public?
Other than traffic control during construction, this restriction will not affect personal vehicles, with the
possible exception of large recreational vehicles (RVs) or trailers. If you have concerns about your
vehicle, please contact MS/CVE.

What is the bridge rehabilitation timeline?
The first phase is expected to begin in early May. The contractor can begin work as early as May 1,
but that timeline is subject to change. Actual start dates will be communicated as construction
season approaches. The first phase of bridge rehabilitation will be the most restrictive with a
regulatory speed reduction to 5 mph at the bridge, traffic delays such as pilot cars, and a width
restriction of 13’3” between rails. More detailed information can be found on the Chatanika River
Bridge work schedule flyer.
After the first phase has been completed, there will be a 96‐hour window during which width
restrictions will be increased to 20’6” with an oversize permit. At this point, regulatory speed
reduction of 5mph will be removed for the remainder of the construction season. We expect this
window will occur in mid‐June. We will communicate the exact dates when they are firmed up during
the first phase of construction. For project updates regarding restrictions and timeline, please
contact DOT at (907) 451‐1679.
The second phase of bridge rehabilitation will begin immediately after the 96‐hour window. During
this phase, there will width restrictions of 13’3” between rails. More detailed information can be
found on the Chatanika River Bridge work schedule flyer.
Will my overweight permit application be approved?
Each permit application will be reviewed individually by MS/CVE staff. Some overweight permits may
require additional measures such as slower speeds and traffic control. We cannot confirm that any
specific weight, configuration, or application will be approved, however, so we encourage you to
submit your permit applications as soon as possible in case you need to make alternative plans.
