Road Innluence Area Singida Shelui Road Section is part of the Central Trunk Corridor, which connects Dar es Salaam with northwestemn Tanzania and with landlocked Rwanda, Burundi and eastern Congo. The project's Road Section extends northwestward from Singida town through Shelui Trade Center until the border with Tabora region, for a total design length of 107 km. The immediate influence area of the Road Section largely coincides with its feeder road basin, covering some 5000 km2 with 250,000 people, of which 150,000 in Singida Urban District and 100,000 in two rural Districts. The population density of the Road Influence Area is 60 inhabitants per km2 (16 in the rural countryside). The land use pattern consists of fallow and grazing areas (52% of the Road Influence Area), thicket (25%), forests of various densities (8%), farmlands (12%) and water bodies (3%). The landscapes traversed by the road display a low cropping intensity, with scattered villages and trading centers. The first 78 km cut across a rolling plateau with sparse cultivations at an average altitude of 1,150 meters, followed by the rugged, densely wooded relief of Sekenke escarpment, rising to higher altitudes from km 78 to 90. After the escarpment, the road cuts across the flat, intensively farmed Shelui plateau. The last three km traverse the uninhabited swamplands of Wembere river, at an average altitude some 20 meters below the plateau. 2. The proposed road-upgrading project The project aims at upgrading Singida Shelui road to bitumen standards, with a 20-year design life for the new sections, 10 for the rehabilitation works. The design route will overlap with the existing one for 86 km out of 110km. The major improvements include: Road geometry: widening to 10 meters from present 7 to 10 Road reserve corridor: 45m in the rural areas, from present 25 to 45 m Design speed: 110 km per hour CalTying capacity: 1300 vehicle/day, up from 280 in the year 2000 Carriage way: 6.5 m wide, with two lanes and a 1.5m shoulder on both sides Pavement: double surface dressing, with a 2.5% camber to bitumen standard Drainage: cross drainage structures with intersection road apartments Bypasses: the design route will avoid Iguguno town (5000 people), reducing the congestion and pollution in this small town, and will bypass the hilly section of Sekenke escalpment, which cut across a dense forest, where the present road is characterized by many traffic accidents and has conduced to the depletion of the forestry cover. 3. Environmental impacts without the proposed project The present road conditions generate a high accident rate especially in the rugged Sekenke sub-section (km 78 to 90). The dirt surface and low vehicle speed cause dusts and pollution in the traversed settlements. The rural landscapes crossed by the road show advanced signs of soil erosion, forest destruction and disappearance of wildlife, due to extensive farming, overgrazing and wood-cutting for the production of charcoal. Due to poor accessibility and high transport costs under the present road conditions, the competent ministries find it hard ExecLitive summary Annex 8 - S. 2 Techniplan Singida-Shelui Road: Detailed Engineering Design FinialReport: Annex 8 - EIA, SIA & RIA Executive Summary to extend sustainable methods of rural production to the road influence area. Moreover, Singida Shelui road section is considered to be the bottleneck of the Central Trunk Corridor, constraining national and international communications through Central Tanzania.
