Scientists suggest that temperatures might rise 5 deg F to 9 deg F over the next 100 years, and that the sea level could rise 2 to 5 ft in response. Temperature change might reduce snow and ice control costs, slow road and bridge deterioration, and eventually reduce required pavement thickness. The uncertainty of future temperatures suggests increasing the safety factor currently designed into expansion joints on bridges and major roads, and reexamining the heat tolerances of railroad tracks. A rising sea level and the potential for more intense storms could require bridge redesign, better airport drainage, and raising of low-lying streets near tidal waters. Retrofitting could be much more costly than changes made prospectively during reconstruction. Design standards and siting criteria should be reassessed in light of likely climate changes.
