The deteriorating condition of aging 80+ year old timber bridges has resulted in weight restrictions for several reaches of National Trails Highway (Route 66).
Department of Public Works' consultant hired in early 2014 provided new weight restrictions on 10 additional bridges due to their accelerated deterioration. New postings were installed in September 2014.
Note: Some sections are restricted to vehicles under 3 tons. It is anticipated that additional postings will occur as further evaluations by the consultant are completed.
