Scientists: Keys road widening partly to blame for algal bloom

Disturbances from last year's hurricanes likely stirred up phosphorus in the water, feeding the algae, but construction widening an 18-mile stretch of U.S. 1 between Florida City and Key Largo may also be to blame, according to a South Florida Water Management District analysis released late last month; the road widening and bridge construction began in April 2005 after a federal judge denied an attempt by environmental groups to block the $268 million project, which the groups said did not meet state and federal environmental standards - Aug. 18, AP
