Evaluate Maintenance Plan Results
5.2 Maintenance will almost certainly occur long past any monitoring, because of the continual need over the life of the crossing structures. Therefore, it is important to review the maintenance plan to ensure that the objectives are being met with regards to the effectiveness of the components of crossing structures. Because the field of transportation ecology is increasing in knowledge rapidly, it is possible that maintenance plan monitoring will show that replacement of some components with new technology is warranted. Consider replacing inefficient and outdated structures to meet the intent of the planners. Consider that the ecological context may change over the life of the crossing structures, and other technologies may be more appropriate in the future.
