More than three-quarters of respondents to a recent survey believe the government should stop building expressways if the projects are not expected to turn a profit.

The results of the survey, conducted by an advisory panel to Prime Minister Junichiro Koizumi, were released Tuesday.

Koizumi asked the panel to draw up privatization plans for four debt-ridden semigovernmental firms: Japan Highway Public Corp., Metropolitan Expressway Public Corp., Hanshin Expressway Public Corp. and Honshu-Shikoku Bridge Authority.
