In 2007 Richland did an engineering study on our causeway.  The detailed and summary results are in the following links.  The essence of the report is that we have many years of life left in our bridges … if they are properly maintained.  In the summer of 2010 we will complete the suggested remediation steps from this study and address any deficiencies in the rip-wrap around our bridge piers.
