When any street works have been executed on any land in a designated area which was then or has since become a private street (or part of a private street), the housing action trust may serve a notice on the street works authority requiring it to declare the street (or part) to be a highway which for the purposes of the Highways Act 1980 is a highway maintainable at the public expense.
Within the period of two months beginning on the date of the service of a notice under subsection (1) above, the street works authority may appeal against the notice to the Secretary of State . . .
After considering any representations made to him by the housing action trust and the street works authority, the Secretary of State shall determine an appeal under subsection (2) above by setting aside or confirming the notice under subsection (1) above (with or without modifications).
Where, under subsection (3) above, the Secretary of State confirms a notice,—
Where a street works authority neither complies with the notice under subsection (1) above, nor appeals under subsection (2) above, the street (or part) concerned shall become a highway maintainable at the public expense upon the expiry of the period of two months referred to in subsection (2) above.
In this section "private street" and "street works authority" have the same meanings as in Part XI of the Highways Act 1980.
