Minister of Stote for lronsport The Permonent Secretory, Ministry of Works ond Tronsport Mission: To promote adeqaatersafe and well maintained Works and Transport Infrastructure and Services for Socio- Economic Development of Uganda REMOVAL OF ROUNDABOUT ON MUBENDE KIBAALE KAGADI ROAD (HON. KTSEMBO BASEMERA WOMAN MP KIBAALE DISTRICT) 1.0 Background Reference is made to a letter from parliament addressed to the Hon.A/inister of Works and Transport on removal of the roundabout on the [/ubende-Kakumiro-Kagadi road. The Government of Uganda (GoU) obtained funds to fund its National Roads Development and Maintenance Programme (NRDIVIP) and parts of the funds have been applied for payments for design and build for upgrading of Mubende-Kakumro -Kagadi from gravel to bituminous paved road. The Mubende-Kakumiro-Kagadi road (107 Km) was previously a gravel road except for a highly patched tarmac road on the first 3.4km in lt/ubende lVlunicipality. lt runs from lVlubende-District through Kakumiro, through Kibaale Districts and to Kagadi District on the Kyenjojo-Kabwoya-Kigumba road. The Project road begins at the l\Iubende IMunicipality near at Total Junction and ends at Kagadi Town. lt forms an alternative route from Capital City (Kampala) to Albertine oil graben region. During design, there was necessity to cut and/or fill in order to meet the minimum design specifications and safeguard safety of motorists and other road iusers. The road has been upgraded to Class ll Asphalt Concrete carriage way of 3.5m wide lanes plus 1.5 meters wide Surface dressed shoulders. The road has been widened in Town sections with wider shoulders of 2m. Major Towns of [/ubende, Kakumiro, Kibaale and Kagadi have been provided with Extra parking space on both sides of the road. 2.0 Major Junctions The road has 5 major junctions namely Mubende-Kakumro -Fortportal road junction, ltlubende roundabout, Kakumiro town (Junction to Buhimba Nyalweyo road which junction was designed and will be constructed under the Buhimba Nyalweyo project), Karuguza roundabout, Kibaale District Headquarters Junction and Sunga Junction. 2.1 Mubende-Kakumiroroad-FortportalroadJunction This was previously a T- junction with Small lsland for traffic separation, it was narrow with difficulties in maneuvering especially for traffic turning off from Fortportal road to Kakumiro. It has been widened to improve maneuverability of the trucks. The current design is a T- junction with Separator lsland to direct traffic turning off Fortportal Road. The design of junction was done in accordance with technical requirements to limit inherent hazard and maintain acceptable traffic capacity. The layout and operation of the junction shall be completed with ability to aid the drivers with good visibility between conflicting movements. 2.2 Mubende Roundabout -1,- This junction was previously a roundabout with smaller turning radius and was very difficult to maneuver for bigger trucks. The roundabout has been upgraded and widening with a bigger turning radius that controls traffic on Mubende-Kakumiro road, lt4ain Street and Nakayima way. Standard traffic signs will also be installed in addition to other speed calming measures like speed humps and rumble strips. This will be completed by end of September 2020. 2.3 Karuguuza Roundabout The junction was previously a Y-junction with several turnoffs to Karuguza Town, Kibaale bypass and access to Bujuni Church. lt was difficult to control traffic and maneuver by bigger trucks. It has been improved with connection to Karuguuza Road, Kibaale bypass and main road. The south bound traffic from Kibaale has been provided with dedicated [Vlubende left lane for easy maneuverability. The Bujuni Church Cathedral road was also connected to main road on the outer side of the curve which has better visibility. The roundabout was essential in order to control speed at the section due to connection to Karuguuza, Bujuni Church and Main road; 2.4 Kibaale District Headquarters Junction The junction was previously a small roundabout with very steep grade approach of B% from Kakumiro side while the Kibaale District HQ - Kagadi road was on flatter longitudinal grade. The heavy trucks from Kakumiro side would fail to re-start if they stop at the top and would roll backwards. The junction has been constructed as Y junction with channelized priority intersection at junction to Kibaale District Headquarters . The south approach to the junction is designed 7.5% slope. The traffic from Kakumiro heading towards Kagadi or Kibaale District HQ will be given priority against Kagadi - Kibaale District. Therefore, the traffic from Kagadi to Kibaale District HQ or Kagadi to Kakumiro shall give way to all traffic from Kakumiro. Traffic from District HQ shall give way to the traffic from Kagadi towards Kakumiro as well as traffic from Kakumiro. Channelization will be done to ensure the turning traffic are staying on their lanes. 2.5 Sunga junction The junction was previously a Y junction with narrow approaches and steep grade from Kibaale road.lt has been upgraded to a 3 leg channelized priority intersection at existing Y-junction The Kibaale - Sunga - Kakumiro bound traffic will have priority against the Sunga village road. lt will be complete with traffic calming signs and speed humps to control speeds at approach -2- 3.0 Safety considerations A road safety audit was carried out for the whole road and the major junction at Kibaale District Headquarters. However due to excitement of the motorists, the speed on the road has increased because the main road from N4ubende-Kagadi is now complete with asphalt. The construction of speed calming measures like safety humps and reflective road signs is ongoing including provision of Splitter lsland to allow smooth maneuvering by motorists. Speeds will be limited to 50 km/h in the towns and villages by providing the speed control mechanisms of speed humps, signs and raised pedestrian crossings; We believe with these measures fully completed and functional which we expect to be done by end of September 2020, the road will be much safer for all motorists. 4.0 Conclusion The proposed roundabout at Mubende and Karuguuza and priority junctions at Kibaale and Sunga will be able to serve wide and long vehicles plus smaller vehicles without excessive encroachment to the shoulders or opposing lanes and minimum turning effort. Furthermore, the current design is in compliance with the tMoWT Design Specifications of 2010. The junctions therefore have been designed in accordance with the Design Specifications.
