  "abstract": "<p>Among the different modes of transport, walking dominates the modal split of daily trips in Addis Ababa, making up more than 62% of total trips. Despite this, most of the streets lack crossing facilities and footways and the problem is reflected with the number of traffic accidents which is increasing every year. Walking suffers from unsafe crossing points particularly along the Addis Ababa lite railway transport with no sufficient pedestrian crossing access and very high probability of fatality, wide carriageway separated by barriers to discourage at-grade crossing and encourage mobility with high speed and the act is stated &lsquo;illegal&rsquo; and punishable, pedestrians avoid to use overpasses and take the risks of jaywalking. Most researches about the city&rsquo;s transport problem focus mainly on motorized traffic and neglect walking mode.<br>\nThe aim of this study is to design pedestrian bridge to the selected high traffic jam roundabout in Ababa City. For this design megenagna roundabout is selected because in this roundabout high traffic jam is observer every day and the area is in a critical condition for pedestrians to cross the road. In this study a total of 53,878 pedestrian is counted to design the circular bridge and the data is counted at the five legs of the roundabout for seven consecutive peak hour days and the governing data were recorded at CMC leg which is 1,510 ped/hr. the existing structures around the roundabout is measured directly on the site and using google map technology. The challenging part of this design is the existing buildings near to the roundabout and the overpass road pass above the underground railway transport limited the design. ETABS version 18 software is used to design the bridge and the final design report of the software is more than 500 pages so the summarized report is used in the report</p>",
