splicing ledgers and rim joists

Hi - I'm planning on a deck that will be 30' long. For the ledger and outer rim joist, should I splice them with a 45 degree cut and make sure that they don't occur where a joist will be? To attach, do I nail them, or maybe a plate?

Thanks in advance for any help that you can offer!

rob,

The ledger can have butt or mitre joints but no need to add a backer to this as it will be firmly attached to your existing rim joist of the home.

Deck rim joists "rarely" require a splice in mid-span between posts so this should not be considered as an option. The 45 degree lap does look nice if you are not intending of adding a finish skirt over the rim. This would be like using 2x10 rim/joists and then install 1x12 or 2 - 1x6's to dress up the perimeter.

Hope this helps!
