Despite a large amount of money channelled into the projects, only 30% could be accounted for, indicating the misappropriation of funds in the project organisations. Other problems, such as budget overruns and project delays, have been experienced because some funds are channelled to organisations outside Kenya while there needs to be more for the country. This study therefore sought to examine the effect of project portfolio management on the performance of Roads Projects in Nairobi City County, Kenya. Specifically the study sought to assess the influence of portfolio risk management on the performance of Roads Projects in Nairobi City County, Kenya, and to determine the effect of the Portfolio Strategic Management on the performance of Roads Projects in Nairobi City County, Kenya. This study used a descriptive research design to collect qualitative and quantitative data. The target population for this data included 118 existing road projects within Nairobi City County. This study employed primary data. A semi-structured questionnaire was used to collect primary data. A pilot study was conducted to test validity and reliability of the research instrument with 10% of the sample size hence 12 respondents. Quantitative data was analysed using SPSS Version 24.s. The study results were presented in tables. The study concludes that portfolio risk management has a positive and significant effect on the performance of Roads Projects in Nairobi City County, Kenya. The study also concludes that portfolio strategic management has a positive and significant effect on the performance of Roads Projects in Nairobi City County, Kenya. From the findings the study recommends that the management of road construction agencies should focus on strengthening the implementation of portfolio governance practices, emphasizing robust portfolio optimization, authorization, and oversight mechanisms for roads projects.
