This research aimed to identify the most critical risk factors confronting the execution activities of roadway construction projects (RCPs) in Saudi Arabia. A survey instrument containing 39 critical risk factors affecting RCP activities employed and delivered to the participants. The data was analyzed using SPSS software. The probability affected the RCPs' objectives (time, cost, and quality), and the risk severity were determined. Time and cost percentages of each activity weighed. The anticipated rates of time and cost overruns discovered. Results showed that the cut and fill of earthwork had the greatest representation, with 34% for time and 32% for cost. Contrariwise, the road safety and roadway furniture had the least percentage representation among all activities. Results indicated that an overall time overrun of 33% was done in (15-20) % of all executed projects. While the participants indicated that (5-15) % of the projects had an overall cost overrun of 31%.
