Project Symphony is an attempt to join the Maxis Highways (abbriviated as MHW) with the Real Highway Mod (RHW) by the total conversion of the MHW. The new MHW will have the specifications of the RHW. It looks like a RHW, it will ride like a RHW but it will be build like an MHW.
Initiated by
jdenm8 and later on joined by
MandelSoft, both NAM Team members, this mod will be a total revamp of the MHW, making it easier to construct than the RHW and will have a slightly more urban look than the RHW. Moreover, this can be a stepping stone to the usage of the RHW. After all, this mod is meant to work along with the RHW and the MIS (Modular Interchange System) for ever increasing flexibility.
If you are new to Project Symphony, please read this post. It will answer many frequently asked questions about the network and its future development, and it is updated regularly. If your question isn't answered by this thread, by all means, ask.

The features:

FAQs1. Can this mod work side-by-side with the regular Maxis HighwayNo. This mod is a complete replacement. However, this is an optional NAM component, so you can choose whether to install it or not.
2. This mod completely replaces my Maxis Highways. Can I keep all of them or do I need to demolish them?Most of the draggable content will be ported over with no problems. Especially there will be quite a lot of diagonal functionality from the first release, something uncommon with other NAM items. However, you probably need to demolish the interchanges, since those are not converted due to lots of modeling work and vast underscaling. However, you will be able to build other kinds of interchanges as a replacement with some help of the RHW.
3. When will it be out?As we from the NAM Team say: it will be ready when it is ready. Seriously, we have no idea when it's fully ready for distribution. Probably it will be included in the next NAM.
4. Will this mod be left-hand drive (LHD) compatible?Yes, it most certainly will, as one of its developers works under LHD
5. What about the Euro textures?They will probably be released simultaniously with the rest of the mod. One of the developers is already working on that front...
6. Why are there no starters on the ramp pieces?This will allow you to build more compact interchanges. Starters tend to be in the way in quite some cases. There will be stubs however. You can use the starters from the RHW for the ramp construction. This decision may change in the future, possibly with the implementation of FlexRamps (of which I don't know how to make them).
7. Will pre-fab style interchanges ever come back?No. The massive amount of time required in making one, the size limits imposed on them, the fact that they would duplicate already existing functionality, along with the rigid inflexibility of such setups, the underscaled dimensions of these interchanges and the massive number that would have to be made in order to account for all the networks both MHW and RHW renders the notion of plop interchanges impractical and unworkable. Semi-prefabs will probably the biggest components that will be realised.
8. How about bridges and tunnels?The current Maxis Highway bridges have proven to be too hard to convert for now, so you have to use avenue bridges instead, or some of the new dual RHW-4 bridges. For the tunnels, there will be a 7.5m high ground level tunnel override available, which will require a custom slope mod (included in the mod):
