ENR Reports that Pennsylvania Route 22/322 now has the longest MSE Wall in the U.S. and Canada, and the 2nd longest in the world. The project is located in Mifflin County, Pa. and involves adding an additional 2 lanes in a bifurcated alignment to supplement the existing 2 lanes in a dangerous stretch of roadway known as â€œLewiston Narrows,â€ between the Juniata River and Shade Mountain. The project also involves approximately 9,000 micropiles, 8,280 linear ft of shoreline retaining walls (nine), and approximately 40,000 ft of H-piles were driven for the retaining wall and for two bridges.

The downloads page at ADAMA Engineering lists an update (Number 1) for ReSSA 3.0. I have not even heard anything about the release of version 3.0, and even other pages on their website only mention ReSSA 2.0 as the latest version. As soon as I hear anything about the new version and its additional features, I’ll be sure to post the info here. ReSSA is software for the design of reinforced soil slopes or RSS.
An update for the MSE wall design software MSEW was also released recently. This update is number 8.1 and primarily updates the way reinforcement database files are referenced, allowing the location of the database file currently in use to be stored in the project file. After recently completing a major MSE wall review using MSEW, all I can say is halleluia! I had to manually locate the database file for every single one of my old runs. This should be a nice fix.
ADAMA Software has released several updates to their popular MSE Wall design software and Reinforced Soil Slope software packages. Update 9 to MSEW 3.0 was posted on April 25. The changes include several updates related to the AASHTO 2007 code, and the option to use either the Simplified Method (AASHTO) or the Coherent Gravity Method (CGM). And there is now an option for considering live load (LL) in calculating Tmax for strength and connection but ignoring it for pullout.
Update 2.2 to ReSSA 3.0 was posted yesterday, May 5 after several itterations of the update were posted during the month of April. The update includes a fix for handling geometries where multiple points have the same X-coordinate but different Y-coordinates. It also allows for the specification of a vertical seismic coefficient as well as a horizontal one. And the latest updates allow the inclusion of the safety map in the printout, include modified calculations of reinforcement quantities, and allow user-selected colors for reinforcement layers that now shows up in the printout too.
