Mechanically Stabilized Earth (MSE) Walls

Often a lower cost and/or speedier earth retaining structure, MSE walls are popular in highway and bridge design. Their component pieces are relatively basic and there are often fewer surprises than with other methods. US 301 in Delaware was constructed over a 3-year period using seven contracts, in addition to advance clearing, tolling, and landscaping. It extends from the Maryland /Delaware State Line to State Route 1, and was opened to traffic on January 10, 2019. It is a 14-mile limited access highway with four interchanges, 28 bridges, and an all electronic tolling (AET) system. The Delaware T2/LTAP Center provides direct technical assistance, training, and technology transfer to Delaware local agencies relative to their transportation challenges. https://sites.udel.edu/dct/t2-center/
