Abstract—Based on the BP neural network, this paper sets up the model of cost estimation of highway engineering. The BP neural network model is trained by a sample data obtained from some performed typical engineering to come true quick cost-estimating．It is sure that the method is practical and the estimating results are reliable according to lots of examples．It shows the promising perspective of BP Neural Network in cost estimate of construction engineering.
