Hello, I recently had a small fire on my front porch from a cigarette hot head that fell between the shingles that are peeling up and the wall. When I noticed the fire it was already inside and had to tear apart the railing. Not being a construction type of person but wanting to learn, I want to fix this myself. At first, I thought I would just patch it, but the more I got inside the more I noticed the burn marks. Now I think that I should just replace the railing with some 2x4s and plywood. However, I have some thoughts that I am not sure about. Since these are only 26" from the porch, should I just make it 36" to meet code? If I do that, then the rest of the railings will not match. Secondly, that top piece is angled and routed and I am not sure I can replicate that. If you had to do this, what would you do? Thank you.

Built a wooden bridge using the following: -Sistered 2x8x16 stringers with carriage bolts (2 boards together on each side). The stringers are 48” apart. -Cross bracing every 24”. -Treads are 2x6s and 5 foot long. - Used treated southern yellow pine for everything. Any idea of load capacity? Tried looking at the tables and websites but unclear. Feels fine for pedestrians but wondering about small equipment (riding mower as example) thanks so much for any advice!
