The Reconstruction of Hummingbird Highway Project The project will comprise four main components: Civil Works, Land Acquisition, Consultancy Services and Supervision, and Project Management. The four components are described below:
Component 1: Civil Works
This component will cover the reconstruction of the 85 km of the Hummingbird
Highway. The construction of 8 new bridges, rehabilitation/reconstruction of drainage
and related infrastructure, safety features, ancillary and utilities structures as outlined
below:
a) Road Works:
i. Widening and reconstruction of a single road carriageway to a double bituminous surface dressing (40mm) with two traffic lanes width of
3.5m each way and a 1m paved shoulder on each side;
ii. Widening works will be conducted at locations with vertical grade more than 6% with climbing lane and widening paved shoulder up to 3.6 m;
iii. Widening works will be conducted at horizontal curves to facilitate flow of highway traffic.
b) Bridges: including the construction of 8 Reinforced Concrete new bridges with pedestrian sidewalks and reinforced-concrete and ferro-concrete box culverts, as well as related furniture, lighting and safety measures.
i. St. Margaret�s Village Bridge: the construction of Reinforced Concrete Bridge with a single span of 30 m. The bridge will be 12 m wide including two traffic lanes with a total width of 4.5 m, pedestrian sidewalks of 1.5 m width on each side and a 40 m safety rail on each side. The bridge will include two reinforced concrete abutments at each side of the riverbank.
ii. Dry Creek Bridge: the construction of Reinforced Concrete Bridge with a double span of 22 m. The bridge will have 12 m width two traffic lanes with a total width 4.5 m pedestrian sidewalks of 1.5 m width on each side. The bridge will include two reinforced concrete abutments at each end of the river bank and a reinforced concrete
intermediate pier.
iii. Little Silver Creek Bridge: Repositioning and construction of a reinforced concrete two lane bridge to facilitate. The single span bridge of 7 m, with two reinforced concrete abutments at each end. The width of the bridge will be 12 meters with two traffic lanes 4.5 meters width and two pedestrian sidewalks of 1.5 meters width. iv. Valley Community Bridge: the construction of Reinforced Concrete Bridge with a single span of 30 m the bridge will have 12 m two traffic lanes with a total width 4.5 m, pedestrian sidewalks of 1.5 m width on each side. The bridge will include two reinforced concrete abutments at each end of the river bank.
v. Light Community Bridge: the construction of a 42 m long reinforced ferro-concrete box culvert bridge (2.7meters by 4.7 meters).
vi. Steadfast Bridge 1: the construction of a 35 m reinforced ferroconcrete of two (2.7m x 5 m) double culvert boxes.
vii. Steadfast Bridge 2: the construction of a 36m reinforced ferroconcrete 2.5m x 4.4 m culvert box.
viii. Alta Vista Bridge: the construction of a 45 m long reinforced ferroconcrete two (2.2m x 4.4 m) double culvert box.
c) Drainage: this includes the provision of lined drainage on both sides of the
highway, the provision of drains in the areas where drains are not available on
both sides or on one side of the project stretch. The type of drains will vary
between, earthen trapezoidal drains, concrete line drains and roadside kerb
drains. In addition, to the provision of culverts and outfall channels for the
purpose of drainage. Existing culverts and drainage points will be
rehabilitated. Vegetation clearance along the existing unlined drains will be
conducted. Drainage clean-up of a small section on a one side lined drain will
be conducted.
d) Ancillary, Safety features and utilities structures: Streetlights will be
installed at inhabited locations and all locations with sharp curves in
residential areas. In addition, Safety features, Crash barrier, rumble strips and
delineator post as well as pedestrian crossings, Bus Lay-bys, traffic Signs,
lighting arrangements and lane markings etc wil
