asked the Secretary of State for Wales what was the cost to public funds in each year since 1970, up to the latest year for which figures are available, of producing road signs in Welsh as well as in English.

Approximate costs, at outturn prices for signs showing both Welsh and English legends erected on trunk roads, are given below:

1974–75	£140,000
1975–76	£60,000
1976–77	£515,000
1977–78	£360,000
1978–79	£360,000
1979–80 (provisional)	£440,000

No bilingual signs were erected on trunk roads prior to 1974. Information about expenditure on signs on county roads is not available. The greater part of this expenditure would have been incurred in erecting. English only signs.
