Page 265. The first contract for part of this work, was let in September and consisted of the removal of over 100,000 cubic yards of earth and rock, the construction of mass concrete retaining walls and extensions to box culverts.

The normal specification for this type of road was 3 inch hardcore foundation, 4 inch thickness of 1$\frac{1}{2}$ inch bitumen macadam with a 1 inch wearing coat of bituminous material.
269. Work was completed on the first section of the 'Road off Boundary Street', originally intended to serve new development to the North of Kau Lung Tong, but following the decision to erect resettlement flats at Tai Hang Tung, arrangements were made to extend it to provide access to that area. The work was divided into three sections, the first 1,000 feet, the second 1,100
