| 摘要： | The 130-mile freeway system in Atlanta was completed in 1967 with typical sections of 4 and 6 lanes. No additional work was done on the system until 1978, when a transportation plan for the city was approved. Its emphasis was on reconstructing the freeway system in Atlanta which had become grossly inadequate due to population growth. The plan called for adding additional lanes to the existing system and constructing a 100-mile rail transit system. Officials identified three major areas of concern: cost, environmental effects, and construction under traffic. Much of the cost was taken care of by Interstate financing, for which Atlanta became eligible for various reasons. The major environmental concern was identified as noise, which was solved by the construction of noise barriers. To solve the problem of maintaining traffic during construction, contractors and construction engineers worked together with the designers and many modifications of stage construction plans were developed where money and time could be saved without compromising safety or existing traffic capacity. The Georgia DOT now has all work either completed or under contract, except for one segment of Interstate 20. All of this has been accomplished since 1978. The total cost to is $1.4 billion. When the project is finished in 1990, 130 miles of urban freeway will have been completely reconstructed in 12 years. This paper discusses in greater detail the reconstruction of some of the main roadway segments. |
