Project Location Map Outline of the Project 1.Country： Ukraine 2.Project Name： Additional Study on the Project for Construction of Mykolaiv Bridge in Ukraine 3.ExecutionAgency： The State Agency of Automobile Roads of Ukraine (Ukravtodor) 4.Survey Objective： Considering the time elapsed since the feasibility study for a Japanese ODA Loan project in 2011, the main objectives of this Study are as follows: ･Reassessment of the project cost (including land compensation and O&M costs), reanalysis of cost benefits, and reexamination of the implementation method (procurement and construction); ･Reconsideration of the applicability of the latest technologies; and ･Confirmation of the environmental and social considerations and other matters related to project implementation under the latest conditions. 5.Survey Contents： (1)Background (10)Environmental and Social Considerations (2)Implementation Flow and Work Process (11)Review of the Construction and Procurement Plans (3)Project Approval Procedure in Ukraine (12)The Safety Measures during the Construction (4)Supplementing Surveys of Natural Conditions (13)Project Operation and Maintenance Plans (5)Review of Routes and Locations of Bridges (14)Recalculation of Estimated Project Cost (6)Review of Road Plans (15)Review of Project Risk Analysis (7)Review of Bridge Plans (16)Consideration of Cost Reduction Effects (8)Traffic Demand Forecast (17)Economic and Financial Analysis (9)Study on the Slope Stability at the Bridge Construction Site (18)Survey of Obstructions and Partner Country Responsibilities 6.Conclusion and Recommendations： (1)Conclusion 1) The Project is technically and economically feasible. 2) Bypass route and the location of Mykolaiv Bridge are changed due to the following reasons. ･The newly selected route has the best economic benefits (B / C), and the location of the interchange at its terminus is the best from the viewpoint of the ring road concept. ･River channel alignment where the bridge crosses is close to straight, therefore it is superior in river condition and inland waterway condition. ･Although there is a possibility of landslide, the range is narrow and the location of the abutment is outside of the landslide area. 3) The cable-stayed bridge with center span length of 420m is the most appropriate for the main bridge based on comprehensive evaluation of construction cost, navigation safety, merits for Ukraine (less environmental impact, possibility of technical transfer), aesthetic feature, construction difficulty and maintenance cost. Steel pipe sheet pile foundation is adopted for foundation based on the same evaluation except aesthetic feature. The center span length is determined from the minimum navigation width of 280m and an additional width (distance from the edge of the navigation channel to the main tower) of 140m. The minimum navigation width is determined with Ukrainian standard based on the maximum size of the vessels; the additional width based on the relationship between the navigation channel width and center span length of cable-stayed bridges in Japan (half of the minimum navigation width). 4) Precast PC slab and steel small number girder bridge with maximum span length of 60m is the most appropriate for the approach bridge based on comprehensive evaluation of construction cost, merits for Ukraine (less environmental impact, possibility of technical transfer), construction difficulty and maintenance cost. PC well method is adopted based on the same evaluation. 5) The Road Width which includes Lane width, Shoulder, Median and Pedestrian walkway and so on is changed to 25.5m for road section and 26.3m for bridge section due to the revision of Ukrainian standards. Maximum longitudinal gradient at bridge section is 2.5%, considering prevention of slipping by cross wind and winter freeze. 6) Cloverleaf type is the most appropriate for the interchange at the origin, considering drivability, safety, impact on farmland, involuntary resettlement, workability, and economy. Half-clover type is the most appropriate for the interchange at the terminus, considering the ring road concept. 7) Since the new route is selected, it is required to conduct the feasibility study by Ukraine again. The necessity of reapproval from the Cabinet of Ministers of Ukraine is currently being confirmed. 8) The execution agency for this project will be the State Agency of Automobile Roads of Ukraine (Ukravtodor). In case of applying for Japanese ODA Loan, the procurement of consultants for detailed design, preparation of tender documents, construction supervision and detailed design including procurement of contractor for construction are expected to take approx. three and half years after signing L/A. The estimated schedule is based on general process and cooperation from Ukravtodor and related organization is required. (2)Recommendations 1) It is necessary to consider the impact of the project on the natural, social, and living environments. Especially, efforts must be made to prevent river contamination, to protect fishery resources and to mitigate impacts along the access roads during the bridge construction work. The construction schedule for bridge section must reflect aspects of measures against impacts on the natural, social, and living environments as well as river freeze in winter. In addition, JICA’s Guidelines for Environmental and Social Considerations have been updated since the previous feasibility study and the latest version was published in 2010. 2) The newly selected route passes through the residential area on the right bank of the Southern Bug River and would require demolition of dozens of houses and relocation of their inhabitants. Therefore, the selection of this route would result in environmental and social impacts not discussed in the feasibility study conducted by Ukraine in 2012. In light of this fact, new approval for the Project is required. 3) The project contains the cable-stayed bridge with the longest maximum center span in Ukraine and application of Japanese technology on superstructure, substructure, and foundation works to envision project cost reduction. Therefore it is recommended to prepare documents for project approval to fully utilize the result of this study. In addition, it is important to select consultants and contractors with advanced technical capabilities and experiences in basic design, detailed design, construction supervision and management. 4) It is recommended that Ukraine continues the landslide monitoring implemented in this Study. Executive Summary Background 1-1 Background Mykolaiv City is the capital of Mykolaiv Oblast, which developed mainly around the shipbuilding industry. The city is located in the southern Ukraine and acts as a key hub of the Black Sea coast connecting Europe and Asia. The city is a transport hub uniting the P-06, H-14 and H-11, which run north and south and the M-14 that runs east and west within the major road network. It extends from the granary of inland areas to the ports of Odesa, Yuzhny and Ilichevsk. As the junction of the said road network, the city suffers from high traffic volumes. Around 35,000 vehicles, both large and of other types, are forced into the city center every day, causing serious traffic jams and declines in the quality of life for citizens. There are two bridges constructed in 1964 over the rivers that traverse the city: the Vavarovsky Bridge over the Southern Bug River and the Ingul Bridge over the Ingul River. However, Since both of the bridges are deteriorating, loaded vehicles weighing more than 24 tons are not permitted to cross them. The loading weight restriction has increased the cost of road transport via Mykolaiv City, exacerbating congestion and hindering smooth logistics. To streamline and expand the distribution network for grain and other products, the city expects a new bridge and an approach road that bypass the downtown area of the city immediately. It is worth noting that the importance of this work has been recognized for quite some time; the first feasibility study dealing with Mykolaiv Bridge Construction Project (hereinafter referred to as “the Project”) was conducted in 1989 by Kyivsoiuzshliakhproekt, which was assigned the study by the Government of Soviet Union. Based on the Ukraine-European Union Association Agreement signed in June 2014, the Government of Ukraine (hereinafter referred as “GOU”) established “the Strategic Plan for Development of Road Transport and Road Infrastructure of Ukraine up to 2020” in December 2015, which highlights the importance of improving and modernizing road networks that take safety and the environment into consideration as a means of boosting the economy in Ukraine. The Project ensures smooth vehicle transportation in line with the plan and improves the road transport network in southern Ukraine. The Project is recognized as one of the priority projects among the five bypass projects under “The State Target Economic Program for Development of
